The thickness of buttering which shall remain on the production buttered member after all machining and grinding is completed and before subsequent completion of the joint shall be required by the WPS. When this thickness is less than

2016年6月29日 · A WPS is a document that specifies all of the essential variables that must be defined and controlled when making a particular weld joint. Some of these essential variables are joint design, base metal types, filler metal types, shielding gases, laser type, and laser settings. A WPS is usually required to be qualified (or proven) through testing.

This part of ISO 15609 specifies requirements for the content of the welding procedure specification (WPS) for laser beam welding processes, including overlay welding. It is not applicable to other processes for cladding (e.g. thermal spraying).

2019年8月30日 · You can combine the PQRS to make one WPS. The 14.22mm thickness limit for "T" and "t" still apply so the WPS that could be written would have to limit the base metal thickness to 14.22mm if any GTAW was used. Another way to think of it is like this. If you were to use each individual WPS on one joint, then the WPS must be valid for the joint.

2024年7月28日 · Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high-energy laser beam targeted on the workpiece. The laser beam heats and melts the edges of the workpiece, forming a joint. The energy of a narrow laser beam is highly concentrated at 10 8 -10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10 -6 sec).

2024年4月24日 · Laser Beam Welding (LBW) This type of welding can be used on metals or thermoplastics. As the name implies, it involves the use of a laser as a heat source to create the welds.

A welder qualified to weld in accordance with one qualified WPS is also qualified to weld in accordance with other qualified WPSs, using the same welding process, within the limits of the essential variables of QW-350.
