What is rotpass in welding?

I think you mean root pass. An example would be when butt welding two pieces of plate together (end to end). You would grind a bevel (angle) along the edge of each plate so when you put them end to end there is a small gap between them except at one small point at the bottom. This gap will be filled with molten weld metal to fuse the two plates. Typically, this gap cannot be filled up by one pass with the weld electrode. The welder will go back and forth along the plate eventually filling the entire gap. The "root pass" is simply the first pass the welder makes.


What is the Different between TIG arc welding and gas welding?

Gas welding basically used for weaker joints(in sheets) and arc welding for stronger one(plates). mobile welding (not in a shop)is the ideal time for arc welding . gas welding is the way to go as far as production is concerned , but requires environment with little air circulation or wind , plus gas bottle , machine , and a short lead , which makes it ideal for shop work answer Gas welding - generally use for welding of thin plates/pipes. Less heat input and less likely to burn off the edge of the plates (undercut). It is a more expensive process because of gas shielding. Arc welding - use for thicker plates usually with larger size electrodes. Higher weld production rate. Shielding by means of electrode coating. Both processes can meet the required mechanical properties usually


Mode of failure of riveted joints?

1)Tearing of the plates between the hole if they are very near to each other 2)Tearing of plate betw.een the edge of the plate and rivet hole if the hole is too near the edge. 3)Shearing the rivet if the diameter is smaller than necessary

How do you bevel a countertop edge using a hand plane?

how to plane a countertop bevel edge The longer the edge the longer the plane you should use. this will help leave a consistent result. set the plane so that you are not taking more than a few thousandths of an inch off each stroke. hold the plane at a 45 degree angle to the surface (most common) and make long steady strokes till you achieve the depth of bevel you desire. Its also a good idea to scribe a light pencil line to indicate the bevel depth.
