q345b steel What is plain carbon steel?

Hot Rolled Plates q345b steel MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.

If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600～650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.

Laser deep penetration welding is to radiate a high-power density laser beam onto the welding material. The material converts the absorbed light energy into heat energy, and is heated to evaporate to produce metal vapor. Under the action of the reaction force generated when the metal vapor leaves the surface of the workpiece, the molten metal liquid flows around and forms pits.
