Hot tap operation is a combination of many variables‚ welding is only one of them‚though it’s critical for any hot tapping operation. Note Hot Tap could lead to serious fatalities if not done properly. Since you mentioned about Shell’s DEP‚ please note these DEP’s are well respected in the industry. That does not mean what’s written is absolutely unquestionable‚ but there’re good rationale on what’s written in the DEP’s.

of performing secondary machining operations on the piece. 2. Welding Operations : There are two types of welding being done: * METAL INERT GAS WELDING ( MIG ): It is a welding process in which an electric arc is formed between a consumable electrode wire electrode and a work piece metal‚ which heat the work piece metal‚ causing them to melt‚and join. Along with a wire electrode a shielding gas is fed through the welding gun‚which shields the process from contaminants in the air. The process

weld you combine two different metals. Welders are needed to build more permanent structures like bridges and pipelines. More than a 100 processes are out there that a welder can use two combine metals with. The welding field is cut into 3 sects welding‚ cutting‚ brazing/soldering. Welding is the combining of two different metals. Cutting is when you use extreme heat to separate the two metals by “cutting” into the metal. Brazing and soldering are relatively the same they are both used in the electronic

programing software now makes programing the CNC-controlled press brakes seamless and very efficient. Assembling (joining of the pieces) is done by welding‚ binding with adhesives‚ riveting‚ threaded fasteners‚ or even yet more bending in the form of a crimped seam. Structural steel and sheet metal are the usual starting materials for fabrication‚ along with the welding wire‚ flux‚ and fasteners that will join the cut pieces. As with other manufacturing processes‚ both human labour and automation are commonly
