Terms Used In Welding

1. Blind jointing;

Blind joint refers to a joint in which no portion is visible, jointing that is performed entirely through the welding process with no visual communication between welders.

2. What is flexible automation?

Flexible automation is a welding technology that is automated and the technology that is utilized is one that offers flexibility in that it is capable of making different products over a short time period it also tend to allow production of different part types with overlapping life cycles.

Flexible automation is welding technology that is automated and controlled robotically, designed for use with complicated forms and applications that need the adjustment of torch angles.

Flexible automation is a manufacturing process where machines are designed to be easily retooled to produce different products. This flexibility allows manufacturers to respond quickly to changes in consumer demand.

The benefits of flexible automation include shortened lead times, reduced inventory costs, and increased plant capacity utilization. In addition, flexible automation can improve product quality and consistency.

There are some challenges associated with flexible automation, such as the high initial investment cost and the need for skilled operator. However, these challenges can be overcome with careful planning and execution.

If you are considering implementing flexible automation in your manufacturing process, it is important to work with a reputable supplier that has experience in this area. With the right guidance, flexible automation can be a great asset to your company.

16. Hot-wire TIG (Tip TIG);

A TIG (GTAW) welding procedure in which the welding wire is mechanically vibrated and electrically charged before contacting the weld pool.

17. Indentation;

The depression that occurs on the outside surface or surfaces of the base metal in a spot, seam, or projections weld.

18. Induction heating;

Induction heating is the method of heating an electrically conducting item (often a metal) using electromagnetic induction and heat created in the object by eddy currents.

19. Inert gas;

A gas that does not generally chemically react with the base metal or filler metal.

20. Joint clearance;

Refers to the distance between two surfaces of a joint that fit together. In brazing, this distance is called what is there before brazing, at the temperature of brazing, or after brazing is done.

21. Joint penetration;

Joint penetration refers to the minimum depth of weld from face to joint, without reinforcement, for groove or flange welds. When a joint is penetrated, the root may also be penetrated.

22. Joint weld procedure;

The components, specific procedures, and standard operating procedures that were utilized in the welding of a certain joint.

23 Lap joint;

Lap joint refers to a lap joint of two overlapping members

24. Lightly coated electrode

A filler metal electrode that is primarily used for the purpose of stabilizing the arc and consists of a metal wire that has been given a light coating after the drawing procedure has been completed.

The temperature point at which a metal or alloy becomes entirely liquid.

26. Machine welding;

Refers to equipment for welding that performs the welding operation while being constantly seen and controlled by a welding operator. The job may or may not be loaded and unloaded by the machinery.

Is the primary bond that keeps metals together and is created in all welding procedures between base metals and filler metals.

When an aggregate of metal atoms is brought close together, the enhanced spatial expansion of the valence electron wave functions results in this primary bond.

34. MIG (GMAW) Welding;

MIG stands for Metal-Inert-Gas, which is also known as GMAW or Gas Metal Arc Welding. A spooled, constantly supplied filler metal (consumable) electrode is used in this arc welding procedure. Externally supplied gas or gas mixes offer shielding.
