New vs. Old Ways of Welding
People may think that welding is an unchanging profession. Joining two pieces of metal can’t have changed much, you might think. Well, think again. There are a lot of differences between the old ways and new ways of doing welding. Let us explain a few.
Modern electrode welding has come a long way. True, not all cases call for an electrode weld, but if you’re out in the field welding rusted, painted metal, electrode welding is preferable to MIG fabrication methods which require more stringent conditions. Today’s electrode (stick) welding can be A/C or A/C-D/C, which allows you to reverse the polarity, changing the direction of the flow of electricity to prevent burn-through on thin metals. Additionally, it’s easier to strike an arc with the electronics in today’s electrode welding and there is often less splatter. These are just some of the advantages of working with today’s electrode A/C-D/C welds.
Increased Efficiency and Power
The two go hand in hand. With greater power comes greater efficiency. The machines of the twentieth century only converted 60-70% of incoming power. Today, with machining and electrical engineering advances, that number can be as high as 85%, particularly if you’re using an inverter-based welder. Utility bills have gone down and efficiency has gone up. Power factors have also increased, meaning that the power you are charged for by the utility company is actually being converted to real power, reducing demand. You’re getting your money’s worth with the newer machines and saving energy. If you’re still using equipment made before Y2K, you might want to think about upgrading.
Higher Quality Output
As with most things, newer equals better. And this is even true for welding. Newer machines are capable of cleaner arcs, more stable and smooth arc, consistent power to prevent defects, and increased puddle control. This all makes for happy welders and happy customers.
