6 FAQs about [Standards for resistance energy storage welding]
What is a welding safety standard?
This standard covers all aspects of safety and health in the welding environment, emphasizing oxygen gas and arc weld-ing processes with some coverage given to resistance and high energy beam welding, brazing and soldering.
How should resistance welding equipment be selected?
All resistance welding equipment shall be selected for safe application to the work intended. The personnel safety aspects of resistance welding shall be given consideration when choosing equipment for the work to be performed. 12.1.3 Operator Training.
What is resistance spot welding?
Resistance spot, ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry. Cell casing and terminal dimensions may constrain possible contact geometries.
What is resistance welding?
Since the “invention” or discovery of resistance welding, over 120 years ago, the definition of the process has remained unchanged. Resistance Welding is a method of joining metals. To join two metals by resistance welding, it is necessary only to clamp them together under pressure and pass through them an electric current for a specific time.
Do resistance welders need voltage compensation?
Resistance welders are more susceptible to voltage changes than other factory equipment. For welding mild steel, generally, a change in voltage of about 20% will not adversely affect the weld quality and voltage compensation is usually not required for welding mild steel.
What are the AIDS to resistance welding?
Other aids to resistance welding are available in the form of weld monitors. A weld monitor can be used to track the performance of various parameters of the welding process once good weld parameters have been established. At this point, the monitor can be used to indicate variations from an established norm.
