Repair Metal Chair With Welding Technique

Indoor Metal Cafe Side Chairs

You will have to practice many times to build an attractive metal chair, but on the other hand, you will not get better if you do not try it. Making a metal chair can be an interesting and challenging project for adults who can work safely with heat sources and welding tools. Repairing a metal chair by welding it back together requires a certain amount of care and attention to detail to ensure that the chair does not break again. While this is a relatively easy process, it is important to remove flammable materials such as fillers or labels from the chair. Once this is done, any MIG welder can be used to quickly apply a solid weld bead to the broken metal and make it as good as new again. Remove all flammable materials from the chair, such as cushions or labels before starting.

Also, if you are not familiar with welding, you may want to wear a long-sleeved shirt and gloves to make the process more comfortable. Pour a small amount of alcohol over the place where the metal has broken, and scrub thoroughly with a wire brush. This will remove any trace of oxidation or other impurities on the metal surface that can prevent the welding electrode from producing a clean, strong braze. Attach the solder’s electrical connection to a metal part of the cheap metal chairs that is less than 12 inches from the spot you are welding. This place must have metal-to-metal contact with the weld repair in order to function properly. Turn on the welder and set it to the size of metal to be welded. In the case of chairs, reducing the speed of wire feed and electrical power to its lowest levels will produce the best results due to the use of relatively thin metal in the chair construction.

Lower your facepiece and position the welding nozzle just above the break in the metal saddle. Use your free hand to pinch the two pieces of metal, very close as you can, then squeeze the trigger of the welder. You will see a metal bath begin to form through the lens of the helmet. Draw the pool of molten metal through the break in the metal chairs outdoor with a sewing motion, keeping the size of the metal cluster about a quarter of an inch in diameter. If the pool gets smaller, move more slowly through the metal. If it’s bigger, speed up. Rub the surface of the weld with the wire brush after you have completed the process.
