1.Definition and influencing factors of welding speed
Welding speed refers to the length or the time required for the welding point to pass through the welding head per unit time.It is an important parameter in the welding process and will directly affect the welding quality and efficiency.Here are some factors that affect welding speed:
Characteristics of the equipment itself:Different models of automatic welding machines have different restrictions and requirements on welding speed.Therefore,when adjusting the welding speed,it must be set according to the requirements of the equipment model.
Electrode size:The size of the electrode head directly affects the size of the welding current,thereby affecting the welding speed.Typically,larger electrode tips result in slower welding speeds.
Type and thickness of metal materials:Different types of metal materials have different welding speed requirements.Generally speaking,thicker metal requires more welding time to ensure good weld quality.
2.Adjustment method of welding speed
In order to adjust the welding speed to meet specific needs,the following methods can be used:
Adjust the welding current:By changing the size of the welding current,the welding speed can be controlled.Generally speaking,increasing the welding current can increase the welding speed,while decreasing the welding current can slow down the speed.
Adjusting the welding voltage:Adjusting the welding voltage can change the electric field strength between the electrode and the workpiece,thereby affecting the welding speed.Generally speaking,increasing the voltage will speed up the welding,and decreasing the voltage will slow down the speed.
Adjust the size of the welding head:By changing the size of the welding head,the welding speed can be adjusted.Larger electrode tips generally result in slower welding speeds,while smaller electrode tips increase speeds.
It is important to note that the correct welding speed depends on the characteristics of the equipment and the type and thickness of the metal material used.In practice,it may take some experimentation and adjustment to find the speed setting that works best for your specific welding task.Hopefully this information will help you better understand the importance of welding speed and how to adjust it for a successful welding job.
