What is a welding inspection?

The inspection of welds and welded assemblies requires knowledge of many factors of welding quality control. This includes dimensional inspection, nondestructive examination methods, welding processes, welding metallurgy, destructive testing, and the qualification of welding procedures and personnel.

Where can I find information about arc stud welding?

In addition, we recommend looking through DVS leaflet 0902 “Arc stud welding with drawn arc” and DGUV information 209-010 “Arc welding”, as well as standards EN ISO 14555 “Welding - Arc stud welding of metallic materials” and EN ISO 13918 “Welding - Studs and ceramic ferrules for arc stud welding”.

What are the requirements for inspecting welding devices?

The requirements for inspecting welding devices are specified in EN 60974-4 (DIN VDE 0544-4) 2017-05 Arc welding equipment - Part 4: Periodic inspection and testing. Defective components and cleaning tasks inside the INTRA 2100/1400 require the welding device to be dismantled.

Do stud welding systems need special care?

The stud welding system requires no special care. The required cleaning tasks for the gun and sorter can be found in the specific devices’ operating manuals. For the INTRA 2100/1400 welding device, the following cleaning tasks are required. Here it should be noted:

When should a weld be inspected?

Large weld diameters 8 mm and above encourage the influence of the blow effect. If visual inspection has shown some welds to be inadequate, a mechanical inspection is necessary. We also recommend this test if you perform a series of test welds to determine the best settings.

How do you determine the optimal weld parameters?

The optimal weld parameters must always be determined in consideration of factors such as material and surface characteristics of the workpiece, sheet metal thickness, welding position, stud type, stud dimensions, etc., through test welds. Make sure the test welds reflect real conditions during the production process as much as possible.
