Welding is a core activity in the fabrication factory, undertaken by skilled, qualified operatives working to a welding quality management system under the control of a Responsible Welding Coordinator. It is used to prepare joints for connection in the shop and on site, and for the attachment of other fixtures and fittings. Different welding techniques are used for different activities within the fabrication factory. Essentially, the welding process uses an electric arc to generate heat to melt the parent material in the joint. A separate filler material supplied as a consumable electrode also melts and combines with the parent material to form a molten weld pool. As welding progresses along the joint, the weld pool solidifies fusing the parent and weld metal together.

Deep penetration welding | TRUMPF
Can a full penetration weld be restored? Yes,the full-penetration weld qualify as full restoration of the original section properties. However,one must be careful. Have a Welding Inspector witness cutting the beam through final weld,i. If you don't witness it how do you know?
How to Make Strong Welded H-beam Connections?
Weld design is not exempt from the numerous differences between wide-flange WF and hollow structural section HSS connection design. Unlike open sections where welding is possible on both sides of the flanges and web, the interior of HSS sections commonly used in building structures cannot be accessed. Complete joint penetration CJP welds are unquestionably the least preferred weld type from a fabrication and cost point of view.
The joint information below helps define and clarify the tooling and fixture options for a new welding project. The square groove butt joint, illustrated in Figure 1, is a basic joint design for electron beam welding. Generally, it is the most practical and most efficient configuration to use.
