Welding Tips & Tricks
Due to the vast number of different welding processes, there are thousands of tips out there to guide any career welder looking to sharpen their skills. Check out some of the diverse advice below concerning these selected processes.
- Keep in mind that clean, dry and oil-free air is very important in the surrounding environment when engaging in this method.
- Remember to keep the air pressure at the recommended level and to not go overboard as more air is not always the way to go.
- Be sure to pause when finishing a cut to guarantee separation.
- The torch should always be perpendicular to the work piece.
Resistance Spot Welding
- Only use this method for steel and stainless steel, as it is not recommended for materials such as aluminum, copper and copper alloys.
- Be sure to use shorter tongs if there is desire to increase the heat.
- Remember to make sure that there are no gaps present between the metals that are to be welded, as this will weaken the weld.
- If it is necessary to have an aesthetic appearance on one side of the weld, the tip on that particular side can be flattened to achieve this.
- Prior to the start of MIG welding, make sure that the ground clamp is in good condition. (HINT: The copper ones greatly surpass their plated steel counterparts.)
- If thin metals are being used, be sure to use a smaller diameter wire and vice-versa for thicker metals.
- Remember to use the proper shielding gas. This will be dependent on the type of metal being used. For instance, Argon should only be used on aluminum.
- In an effort to evade poor wire feeding, keep the gun as straight as possible.
- The TIG torch should be held at a 70 or 80 degree angle.
- Be sure to avoid touching the tungsten to the work piece or it will taint the material and the tungsten will need to be reground.
- As a method of practice for controlling the heat, use the foot pedal to see the weld puddle increase and decrease. It usually works best if the weld puddle is about ¼ inch wide.
- The filler metal should be held in the opposite hand and should be resting horizontally at a 15 degree angle from the work piece. Do not point down.
