e-450 welding
How can we control cracking of E-450 carbon manganese steel?
parameters are:
V:26-30v
A:500-550amps.
T.s.(N):0.25mt/min
just tell me how to control not why it occurs..

zaveriThe speed can be reduced.

got any ideas ? -
CE DesignerIt could be a number of things:
- try pre-heating the piece before welding and post heating after welding to reduce the internal stresses
- you could be using the wrong welding rod also
- let the weld cool in atmosphere. Rapid cooling will cause it to crack
