DP is not actually to do with welding it is a form of NDT which stands for non destructive testing; DP is dye-pen where a white liquid formation is placed over the weld & a normally red enhancer is then placed over the top; this then identifies surface cracks.
Your question is incomplete. Which process? Which electrode? What is the basemetal, which position? etc etc
TW = thermite welding, a welding process that requires no external source of heat or current.
Arc. It's where electrical resistance is used to create the heat for the welding process.

Filling pass is a welding process which function to filling filler metal inside welding groove before capping process be execute
TW = thermite welding, a welding process that requires no external source of heat or current.
it is type of a non ferrous welding process,
TIG welding uses Argon.
DP means De-pledging, essentially dropping out of the pledge process.
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
Oxy-fuel welding is a welding process that requires O2 gas. It uses oxygen and a fuel gas, such as acetylene, to create a high-temperature flame for the welding process. The oxygen supports combustion and helps create the heat needed to weld the materials together.
Arc. It's where electrical resistance is used to create the heat for the welding process.
There are a few commonly used welding process. The top used are shielded metal and arc welding.

filler materials are used to fill the gap between the two job materials during the welding process
