It’s no secret that there can be a big difference in weld quality, depending on the operator. You can blame the tools all you want. But at the end of the day, a good welder can get clean, smooth results even from crappy equipment. Here are a few tips to get you on the road to welding nirvana. ใบเจียร
Tip 1: Use An Auto Darkening Helmet
Do you like grinding? All those sparks, discs and hard work? Didn’t think so. Well getting an auto darkening helmet can really reduce the amount of grinding you have to do. That split second between starting welding and your flip down helmet coming to position, or heaven forbid, you get your hand held mask in position, can have you travelling off your intended welding path. And that means grinding, lots of grinding. Couple to this the fact that auto darkening helmets have really dropped in price in the last few years and you’d be crazy not to grab one.
Tip 2: Two Hands Are Better Than One
Now that you’ve regained the use of both hands, that is if you were using a hand held mask, you can put that extra paw to good use. I know what you’re saying, real men use one hand. But two hands can be steadier, thus producing cleaner, higher quality welds. You can even use one arm steadied against piece being welded to support the neck of the torch. This isn’t a position you can maintain for long periods as it gets way too hot, but in short bursts it works well.
Tip 3: Good Prep Leads To Good Welds
Remember your mother telling you to wash your hands before dinner? Well the same is true for welding. Not the washing hands bit, but the cleaning beforehand. For a good weld to occur you need the surface of both pieces to be rust free and clean. This not only makes the welding easier, it actually improves the weld. Dirty surfaces lead to contaminants getting into the weld and weakening it. But don’t just stop at cleaning the weld area, make sure you clean the clamp position as well. You can use an angle grinder to easily remove most rust, dirt and paint. In harder to get spots you might want to use a dremmel.
