Smaw Uphill Welding Techniques
- 7018 rod has a very quick "puddle freeze" time. In other words, the molten metal that follows the welding rod around dries quicker than with other rods. For this reason, it is a good rod for uphill applications. It can be moved faster than 6010 in weave patterns, but 6010 has much the same properties. 6010 rod is normally used when the metal is not in good shape, such as in the presence of rust or other debris that simply will not come off. However, 6010 is a tad more difficult to work with, and takes more time to learn.
- When you are welding uphill, the rod should always be moving back and forth, which helps the puddle freeze up. This will aid in moving higher and forming new welds on top of each zig-zag. Hold the rod at about a 15-degree slant, with your hand being lower than the tip of the electrode. Each time you zig-zag and reach one of the sides, pause for a second and then drag the electrode back through the puddle to the other side, moving slightly upward each time.
- Because the weld puddle needs to freeze as quickly as possible, you'll want to set the welder for cooler welding, but move the rod slower. That way, there is much less chance of the weld puddle actually dripping molten metal down the weld surface, onto your feet or the shop floor. If the puddle is glowing too much or dripping, move a bit faster. If you are not getting proper penetration in the weld, turn the machine up, but only slightly. If the metal gets too hot then welding uphill becomes extremely challenging.
Try 7018 Rod First
Always Use a Zig-Zag Technique
Use a Low Current Setting and Move Slowly
