Spot Weld

Spot resistance welds are usually used to

connect thin plates and thin-walled parts. They

are especially very useful in lot production. The

connections with spot welds are not very

appropriate for transferring high forces. In view

of the type of stress, we distinguish two basic

types of connections with spot welds:- connections with welds stressed in shear (lap

oints!connections with welds stressed in tear

(by tension!

#lug Weld

#lug and slot welds are usually used for lap

oints. They are not suitable for the transfer of

high forces and are especially not suitable for

dynamically loaded connections. The

connection is formed by the weld on walls ofcircular or oval openings and in the contact

surface of the adoining part. #lugs and slots of

small dimensions are usually fully filled with

the weld.

Slot Weld

$ weld between two members, one containing an elongated hole through which the other

member is e%posed& the hole is completely or partially filled with weld metal, thereby

oining the two members& one end of the hole may be open.

Similar to plug weld, but the hole is elongated and may e%tend to the edge of a member

without closing.

'utt Weld

'utt welds originate in the oint gap of

connected parts and are usually used as load-bearing, force welds. In order to achieve

perfect wormanship of the welds, it is usually

necessary to perform modification of the

contact surfaces of the connected parts. The

method of welded surface treatment is set by

the wormanship of the connection, the

thicness of the welded parts, the welding

method and the accessibility of the welded

spot.
