Instructions of Using Stick Electrodes
Storing Stick Electrode
1. Electrodes in unopened package retain the proper moisture content when stored in good
condition.
2. Once the package is opened, electrodes should be stored in a cabinet at 120°-150°C.
3. Dry the electrodes at 300-350 for 60 minutes, and keep at 100-150 before welding. If
exposed to humid air for excessive time, electrodes may pick up enough moisture to affect
operating characteristics or weld quality.
4. Over-drying could damage the electrodes. Please -dry condition for stick electrode
(page )
Welding Procedure
1. Please check welder before welding. Insulate yourself from work and ground.
2. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the
breathing zone.
3. Clean up the contaminations on the work piece to prevent welding defects.
4. Arc strike or re-strike of low hydrogen electrodes should be performed with back-step method
(refer to page 1-8).
5. Choose proper welding current to prevent large spatters or poor weld quality and
mechanical properties.
6. Keep proper width of weaving to prevent slag inclusion and undercut.
7. Apply proper preheat and Interpass temperature to prevent cracks in welds and HAZ when
low hydrogen electrodes are used to welding mid/thick plates.
8. Low hydrogen electrodes should be applied to the base metal with higher carbon, phosphor
or sulfur content.
9. The X-ray quality welds is improved if the joints are ground before the root pass welding.

Instructions of Gas Metal Arc WeldingWelding Instruction
(1) Use a CO2 shielding gas corresponding to ANSI/AWS A5.32/A5.32M SG-C or an equivalent CO2 gas purified for welding.
(2) Control the mixing ratio of Ar and CO2 in an Ar-CO2 admixture shielding gas because fluctuation of the mixing ratio affects the usability of a solid wire.
(3) Adjust the shielding gas flow rate in the 20 to 25 l/min range.
(4) Use a wind screen in welding in a windy area because a strong wind causes blowholes.
(5) Use a proper ventilation system at where general ventilation is inadequate.
(6) Keep the tip-to-work distance at around 15 mm with welding currents less than 250A and at around 20 to 25 mm with welding currents over 250A.
(7) Store welding consumables in a warehouse where the humidity is low.
(8) Use downward welding in the inclined position or forward welding on thin sheet. (Refer following figure)
(9) Impropriate transportation way causes clamp of wire and spool deformation during transporting plastic spool and basket spool.

Drum packageArrow Pack is a pail-pack of large amounts of flux-cored wires and solid wires for gas shielded arc welding, in which the wire is spooled into the drum from its bottom to the top in coil by a unique way. The wire is spooled to be elastically twisted in the pail so that the wire can be pulled out straight without rotation of the pail. The wire makes good tracking on a welding seam. The use of Arrow Pack wires can reduce the downtime for changing wires when compared with conventional spooled wires, which is effective particularly for robotic welding and other automatic welding.

Instructions of Gas Tungsten Arc WeldingFeatures
Advantages of gas tungsten arc welding are less spatter, stable arc and excellent bead appearance. Tips for better welding results in Gas Tungsten Arc Welding
(1) Use the DC-EN connection with the constant current or drooping characteristic DC power source in general applications.
(2) Use an argon gas with a high purity to prevent pits and blowholes in the weld metal and decrease consumption of tungsten electrode. Adjust the shielding gas flow rate in the 12-18 l/min range.
(3) In order to keep the shielding of molten weld pool in good condition, the extension of a tungsten electrode from shielding nozzle should be approx. 5 mm. Maintain the arc length at 2-3 mm. The use of an excessively long arc length can deteriorate the shielding effect
and causes undercut.
(4)Because the quality of gas tungsten arc welds is markedly affected by dirt on groove
surfaces, scale, rust, water and oil must be removed before welding because they cancause pits, blowholes and unstable arcs.
(5) Use a wind screen in a windy site to maintain the shielding gas in good condition. Use an appropriate ventilation system where welding is carried out in a confined area to prevent welders from oxygen deficiency.

Instructions of Flux-Cored Arc WeldingFeature
Flux-cored wires offer excellent weldability with good arc stability, bead appearance, slag
removability and low spatter generation. High deposition rates and welding efficiency of wires are due to high current density, as shown in figure 1.
Welding Instruction
(1) Store wires in a warehouse where the humidity is low.
(2) Because the wire is softer than solid wire, do not excessively tighten the pressure roller of the wire feeder so as not to cause the deformation of the wire.
(3) In flat butt welding, backhand technique is better for stable penetration. In horizontal and overhead fillet welding, forehand technique is better for flat bead appearance.
(4) In vertical down fillet welding, the first layer run should be straight and keep the welding speed faster to avoid slag inclusions and to get better penetration. For the 2nd and subsequent layers, remove the slag of preceding beads and avoid weaving, refer for figure 2.
(5) Use a proper ventilation system at where general ventilation is inadequate.
(6) In one-side welding, welding parameter should carefully be selected to prevent welding defects such as hot cracking.
(7) Use a wind screen when wind velocity is more than 2 m/sec for gas shielding and 10 m/sec for self-shielding, respectively.
(8) Use a CO2 shielding gas corresponding to ANSI/AWS A5.32/A5.32M SG-C or an equivalent CO2 gas purified for welding.
(9) Other instructions refer to P2.16 and P2.17.

Instructions of Submerged Arc WeldingFeature
Submerged Arc Welding is the combination of flux and wire. Wires include solid wires and flux cored wires. Flux is classified as fused and agglomerated flux.
Welding instruction
Accuracy of groove sizes:
The accuracy of root gap and groove angle affects the quality of welds much more than with other welding processes; where the accuracy is poor, burn-through, lack of penetration, excessive or insufficient reinforcement can occur.
Surface of groove:
Rust and oil in the groove must be removed before welding to prevent pits and blowholes.
Storage and dry:
Store flux in a warehouse where the humidity is low. Before use agglomerated flux, the flux must be dried at 200~300 x 1hr and fused flux must be dried at 150~350 x 1hr.
Distribution and circulation of flux:
Where a flux is supplied excessively on the base plate, the bead appearance becomes irregular particularly in use of melted fluxes. In case where a flux is used repetitively by means of a circulation system, the flux can be contaminated with scale and dust and its grain size distribution can be varied; therefore, add new flux occasionally to maintain good performances of the flux.
Grain size of flux:
Sever grain sizes are available for a certain melted flux. The most proper size depends on welding currents to be used. The use of high currents with a coarse grain size flux can deteriorates bead appearance; in contrast, the use of low currents with a fine grain size flux can cause pock marks because of poor degassing.
Welding condition and penetration:
Submerged arc welding can use a wide range of parameters such as wire diameter, welding current, arc voltage and welding speed; however, erroneous setting of theparameter causes burn-through, and insufficient or excessive penetration and reinforcement. The bead shape can be affected by the travel angle of a wire; that is, where the wire is leaned to the direction of welding (backhand welding), the bead shape becomes narrower with comparatively deep penetration. In contrast, where the wire is leaned to the opposite direction of welding (forehand welding), the bead shape becomes wider with shallower penetration.

Submerged arc flux and wire for High Tensile Strength Steel
Submerged arc flux
Kuang Tai manufactures three types of submerged arc fluxes:
(1) acidic flux: KF-330, (2) neutral flux: KF-550,(3) basic flux:KF-990.
KF-330 It has excellent performance characteristics, including very good slag removal, making it
the most common choice for a variety of applications. The faster freezing of KF-330 slag
minimizes spilling on roundabouts. It is designed for welding on rusty or scaly sheet steel
and single arc high speed welding.
KF-550 General purpose flux designed to weld butt joints and both single and multiple pass fillets.
It can be used for automatic and semi-automatic welding. It provides good impact
strength and slag removal
KF-990 It has good operating characteristics and produces excellent impact properties when use
KW series wires and is the ideal flux for most double ending applications.

Instructions of Welding Stainless SteelFeature of stainless steel
The corrosion resistance of these steels, which is based on the passivating effect of chromium due to the formation of dense, adhesive, thin passive films, is brought about by Cr contents above 12 %.Stainless steels are also classified by their microstructure:austenitic, ferritic, martensitic, precipitation-hardening martensitic and duplex stainless steel. The common austenitic stainless steels, such as Type 304, have lower thermal conductivity than carbon steels and this is useful in applications such as cappuccino cups and thermos flakes. Their rate of thermal expansion is also greater than ordinary steel.
Welding instruction for stainless steel1. Arc length:
Nitrogen and oxygen enter into weld metal and reduce ferrite content when arc length is too high. Therefore, keep the arc as short as possible.
2. Welding current:Use proper welding currents because the use of an excessive current causes
overheating of the electrodes and thereby welding usability and weld metal mechanical properties can be deteriorated.
3. Groove cleaning:Cleaning should be done just prior to welding to prevent the formation of oxides.
The groove surface must be free of grease, oil, paint, dirt, etc. A clean surface will provide a smoother, stronger joint. Brush the plate surface & edges with a stainless steel wire brush to remove burrs & oxides. Gloves should be worn to prevent hand oil or dirt from getting on the joining surface.
4. Distortion control:Distortion of stainless steel is very large after welding process. Several
techniques can be used to reduce weld distortion, such as controlling heat input, using clamp and changing welding process.
5. Crack prevention:Welding austenitic stainless steel with low ferrite content is easy to produce the
crack at high temperature. It is noted that arc crater should be filled to avoid crater crack before extinguishing welding.
6. Heat treatment:The preheating, interpass temperature control and post welding heat treatment
are not necessary when welding austenitic stainless steel. Use higher travel speedto avoid the effect of excessive heat input and carbide precipitation. However, the preheating, interpass temperature control and post welding heat treatment are necessary when welding ferritic stainless steel.Take extra caution when performing the heat treatment to avoid carbide precipitation included cracking and distortion.

Stick Electrode for Cast Iron
Instructions of Welding Cast Iron
1. When cast irons have impregnated oil, the base metal must be heated at 400°C to
burn off the oil before welding. Other contaminants should also be removed off
before welding.
2. Stringer welding with the maximum bead length of about 50 mm is recommended to
prevent overheat, distortion and cracking.
3. Peening is needed to minimize residual stresses. Just after one bead was laid, it
must be peened with a hammer to the extent that the ripple of the bead disappears.
4. To repair a defect, it must be removed completely by machining or grinding (arc air
gouging is not suitable for cast irons) before welding. The welding groove should
have a round bottom for better fusion. Where a crack defect seems to be
propagated by machining or grinding, make stop-holes at both ends of the crack.
5. Ni-based cast iron electrode is good for welding in working piece that is no preheat
requirement or small area welding.

Stick Electrode for Arc Cutting
Instruction
Air carbon-arc cutting (ACC) is a process of cutting, piercing, or gouging metal by heating it to
a molten state and then using compressed air to blow away the molten The equipment consists of
a special holder, that uses carbon or graphite electrodes and compressed air fed through jets built
into the electrode holder. A push button or a hand valve on the electrode holder controls the air jet.
Welding Instruction
1. Extend the carbon electrode less than 6"(150mm) beyond the holder to prevent heat buildup
decreasing. While using, the recommended the length of carbon electrode is 3"(75mm) as carbon
or graphite electrodes become smaller.
2. Generally, the electrode is operated with the electrode positive and the metal is melted and
removed quickly.
3. The glass of mask is No.12~14 perfectly.

Welding Backing Material
Ceramic Backing Tape
--------------------------------------------
Introduction
1. Designed for general welding, weld backing tape produces smooth and homogeneous bead
by supporting the puddle and forming back beads during plane welding.
2. Weld backing tape speeds production, improves worker efficiency and reduces costs.
3. It allows one-side welding for steel, alloys and aluminum of any thickness. The product is
composed of ceramic tiles attached to aluminum tape on which specific heat-resistant
adhesives are spread, shown in following figure.
Welding instruction
1. The crack occurs in the first pass weld as use high current/ speed welding.
2. Shrinkage hole and crack occurs as stop welding. They should be removed with for post-weld
grinding and cleaning before re-welding .
Base Metal
The backing tape would be ideally used for welding in mild, alloy steel, stainless steel and
non-ferrous metal
Applications
It is suitable for one-sided welding of deck, strake, shell plate, bridge and box-beam, such as
shipbuilding, boiler/vessel storage tank, fabrication and non-ferrous metal industries
