Question

preparation of lap joint using arc welding process with diagrams
​

Answer 1

Answer:

Explanation:

When do you need to prepare a joint for welding? A rule of thumb is to prepare the joint (bevel it) if the plate is 3/16 thick or more. Some say 1/8 of an inch more. In the Tee joint image above no beveling was needed. But regardless of the metal thickness you still have to prepare it by cleaning it and removing rust, oxides, mill scale etc.
