Welding Tips on a Windy Day!
Just like any tradesman, a welder strives to make their next weld or piece of work better than the last. Whether it be for an employer or just for the farmer down the road, every weld is like the signature of each welder. This article mainly focuses on "Gas Metal Arc Welding" or GMAW. This type of welding is usually done with wire instead of a rod and you must keep your sheilding gas from blowing away and causing holes or "porosity" in your weld. These are just a few small tips and tricks that I have learned in my welding experiences.
- Inspect the Flowmeter
Always check your flowmeter on your shielding gas tank. A poor quality meter or just one that isn't working right, can always cause you problems. Sometimes welders turn their meter all the way up, thinking that they will weld better with more gas. The problem with that is most flowmeters have a diaphram that becomes split or busted when it is turned all the way up. It is a good practice not to turn your meter up really high, this prolongs the life of it and saves you a lot of headaches while welding.
- Keeping Gas Nozzle Clean
The gas nozzle on the welding gun is one of the most common causes of holes in your weld. Sparks and welding slag build up on the nozzle and greatly restricts the shielding gas flow to the weld. A good habit is, looking at your nozzle during breaks or periodically during your welding. Most hardware stores sell welding pliers that make cleaning the nozzle almost hassle free.
- Close to the Work?
If you don't have to use a long gas hose, it pays not to. If you are working close to your shielding gas tank, you should use the shortest gas hose possible. Doing this will doing this will cut down on pressure loss, which means better performance of the sheilding gas at the nozzle, where it is needed the most.
- Welding in the Wind
I have learned a small trick that can be helpful when welding on a windy day. Turn the welding nozzle so that the sheilding gas is pushing against the wind while your welding. This don't work all the time, but it will help most of the time. By doing this, it makes the gas kind of fight against the wind and keeps the weld sheilded longer and prevents holes in the weld.
With climbing prices on supplies, these tips could possibly cut down on the shielding gas prices individuals are paying. Hope this helped, or maybe even got you interested in welding if you wasn't before.
