(Overhead Welding Position)Įach position has its own advantages and disadvantages. The six Welding Positions for Groove Welding of Pipes & Plates are : This welding positioning system is used in AWS & ASME welding codes for welder and procedure qualifications. There are six standard welding positions, which are named according to the angle of the part to be welded. For example- in a horizontal, vertical, inclined, flat, or overhead position.

Welding positions are the various ways that you can keep the test coupon or part during welding in terms of inclination angle, rotation, and slope.Ī Welding position defines how a job is positioned for welding. To better help you, we’ve included a video below that demonstrates it perfectly.9.5 What is the most difficult welding position? Welding Positions Improving the strength of the weld and reducing the chances of a defect.Īs we said before, this is the basic explanation of how to make the plug or rosette weld. Doing this allows the base metal to come up to temperature with the top metal. The most important thing to remember is to start on the outside along the edges, working your way towards the middle. Step 5: Now the final step, placing the weld. This is best done with a plug weld clamp. Step 4: After making the holes, you’ll need to clamp the metals together so they don’t move around while you’re welding. This can be done multiple ways, but most of the time welders just use a drill. Step 3: Using the marks you made on the top metal, start making the holes for the welds to be placed. If you’re placing multiple plug welds, they will need to be spaced out evenly. Step 2: Mark out on the top metal where you want to place the welds. The last thing you want is to get a welding burn on something small like a plug weld. Also please make sure to be wearing at least a welding helmet and gloves. You’ll need to clean the metals off so you don’t end up with any welding defects. Step 1: The first step is obviously to prep. Things can vary depending on the job, but you’ll probably be given something to refer to. However, the instructions given below will be just going over the basics. It’s finally time to get to the fun part, learning how to make a plug weld.
