Greetings all from New Zealand.
I did a quick search of the forum to see if I could find the information I require with no result. Does anybody know what external temperature a 3 phase Mig welding torch swan neck will reach during use please?
The reason I ask is: I'm currently writing a historic case study regarding an OTC Daihen DR4000 Mig welding robot I used to operate. If the welding program was recorded while the Mig welding torch was cold, after a few welds, due to thermal expansion of the copper swan neck, the welding position would change resulting in missed welds which then required rework and adjusting the welding torch position in the program. The solution was to run a warm up program consisting of two 500mm long weld beads prior to programming or welding operations to allow the torch to thermally expand as it reached its working temperature.
If I still did Mig welding, I would use an infrared thermometer to record the temperature.
Thank you in advance to anyone who can help.
Kind regards,
Michael.
