6 Potential Assembly Issues
While assembling the final weldment out of the various parts, you may encounter several different issues.
Fitting
Unfortunately, not all parts fit exactly as designed. There may be slight imperfections or distortion, but some problems can be solved by grinding or with a small tack weld.
Weld Distortion
Larger welds may cause weld distortion and have larger heat-affected zones. All metals distort by expansion when heated and contraction when cooled.
There are two main factors affecting the degree of distortion: the rate of thermal expansion and the rate of thermal conductivity. There are also factors affecting the degree at which distortion occurs during welding: heat input, shrinkage of the metal, uniformity of the weld, size of the weld, and whether the parts were offset before welding.
