1. Welding gap
Welding gap is also called butt gap, which is the gap between two weldments at butt joint of weldment. The welding gap is directly related to the quality of welded joint.
When the welding gap is too small, the weld is not easy to be penetrated; when the welding gap is too large, the welding difficulty is increased, the filling amount is large, the welding progress is affected, the welding stress is increased, and the welding deformation is easy to occur.
2. Blunt edge size
Blunt edge size is also called groove size. For U-shaped groove, it also includes the size of arc R.
Too large or too small blunt edge will affect the welding quality, too small blunt edge is easy to cause burn through, too large blunt edge is easy to cause incomplete penetration. If the blunted edges on both sides of the joint are too large or too small at the same time and relatively easy to handle, the penetration can be controlled by adjusting the current. If because one side blunt edge is big, another side blunt edge is small, if use small current, can not weld thoroughly. If large current is used, it will burn through. Therefore, this situation should be paid enough attention to especially in the welding work of single side welding and double side forming.
U-shaped groove is a kind of groove form which can save welding materials, but the size of arc r must be right, and the welding rod or welding wire can easily extend to the bottom of groove for welding.
