The higher the temperature of your brazing alloy, the easier it will be to fill gaps in your metal joints. The main problem is that some of the key components needed for brazing like the flux and an argon shielding gas are not readily available in any form other than welding argon and flux cored wires. The following types of metals are commonly used as filler metals: Dont let tight fittings cramp your production. This Tig stands for Tungsten Inert Gas, and as the name suggests tig welding involves a tungsten electrode to form a strong bond between metal pieces. I've done it before to link a steel shaft with mystery metal X that looked like steel but would just blow up when you started to melt it (I'm guessing its iron/bronze) and it held up fine. The reason why we must use flux cored wire for this operation is that we need a relatively high amperage after which it delivers its self-contained shielding gas mix and powdered flux all at once. Suitable well. In the field of welding, many different subcategories can be formed such as arc welding for example. Provide 7-8 seconds of inert gas post-flow. doing repairs on exhaust tubing, crankcases, or old aluminum sheet). Lets answer the same question as before, can you braze with a MIG welder?
