Disadvantages of Scratch Start TIG Welding

Scratch Start TIG Welding – Limitations and Drawbacks

Scratch start TIG welding is a popular welding technique. But, it has certain limitations that make it unsuitable for special needs.

  • Arc stability is difficult to keep: To start an arc, welders must keep the tungsten and the workpiece in touch. Poor accuracy and control can lead to a wobbly arc.
  • Excessive heat causes metal distortion: Scratch start TIG welding produces more heat than other TIG methods. This causes more distortion of the metal.
  • Risk of tungsten contamination: Scratching the electrode can contaminate the tungsten electrode and cause problems with weld quality.
  • Limited amperage control: Compared to foot pedals or remote controls, scratch start has limited range of amperage control.
  • Precise finishes are hard to get: Maintaining gap distance from workpieces requires skill. This makes it hard to attain precise finishes.
  • Beginner-unfriendly: Material preparation needed for scratch start welding needs attention. So, it is harder for beginners to master.

You must consider these factors when selecting a welding method. However, scratch start may be useful in certain areas such as fieldwork and small repairs.

For example, a welder attempted Scratch Start on some piping without preparation. He couldn’t adjust the amps setting on his starting machine. He then had difficulty controlling directionality, leading to distorted welds.

Frequently Asked Questions

What are the advantages of scratch start TIG welding?

Scratch start TIG welding is the most economical TIG welding option and is better suited for welding thicker metals because it can create a deeper weld penetration. It is also ideal for welding in areas that are difficult to reach.

What are the advantages of lift arc welding?

Lift arc welding is more precise and produces a cleaner weld because the electrode is not touching the metal and creating contaminants. Lift arc welding is also better suited for welding thinner metals because it produces a shallower weld penetration that is less likely to warp the metal being welded.

What type of welding process is preferred for beginner TIG welders?

Lift arc welding is the preferred welding process for beginner TIG welders because it is easier to control, produces a cleaner weld, and is less likely to cause warping of the metal being welded.

What type of welding process requires less skill?

Scratch start TIG welding requires less skill and can be more forgiving than lift arc welding because the electrodes can be used to create a deeper weld penetration, which can mask slight mistakes in welding technique.
