MIG welding aluminum is distinct from MIG welding metal. The 1, but important distinction which we’re interested in is always that MIG welding aluminum is simply tougher. That’s due to the fact aluminum welding exaggerates the difficulties with welding another steel like metal. You will discover issues the place aluminum is simply unique. For instance, aluminum welding needs that you simply use pure Argon as shielding gas. Aluminum also needs the voltage and speed settings to be significantly much more exact than with metal. Firearm angle also plays a major position when you aluminum weld.
Here are 5 ideas to aid you get the best out of aluminum welding.
1. Use a spool weapon – A spool weapon really should get rid of the issue with the kinks and binds which are collected inside the MIG weapon by the MIG lead. A Teflon liner or unique torch may perhaps also get the job done, but the best alternative is often a spool weapon.
2. Push do not pull – Pushing works much better and enables the steel to be cleaned by the arc. Pulling outcomes in soot. But in situation you do have to use pulling, you really should clear the get the job done area utilizing a stainless metal brush before you start welding.
3. Use argon or even a helium argon combine – Pure Argon will be the gas of choice for MIG welding aluminum, but you may perhaps also use a 50/50 mixture of Argon and Helium.
4. Use a lengthier stickout – MIG welding aluminum makes use of spray switch. A lengthier stickout will let the spray switch get the job done much better. Plus you’ll save a great deal of ideas.
5. Wire feed speed really should be higher when you begin, and later decrease it as you go.
Learning how you can weld aluminum is often a challenge, even if you are skilled in welding other varieties of steel. The perfect method to understand it is to begin undertaking it.
