What are the Main Arc Welding Objectives?

Arc welding is a welding process that is commonly used in the fabrication industry. It is an economical and efficient way to join two pieces of metal together. In this process, an electric arc is used to generate heat that melts the metals, which are then joined together. However, in order to ensure that the weld is of good quality, there are certain objectives that must be met. In this article, we will discuss the main arc welding objectives.

Arc Welding Objectives

  • The main objective of arc welding is to create a strong and reliable joint between two pieces of metal.
  • The weld must be able to withstand environmental conditions, such as temperature changes and exposure to chemicals.
  • The welding process must also be cost effective and efficient.
  • The weld must be of good quality, with no cracks or other defects.
  • The weld must be strong enough to resist any external forces applied to it.
  • The weld must be aesthetically pleasing, with no visible blemishes.
  • The weld must also be safe, and must not pose any risk to the workers or the environment.

In order to meet these objectives, certain precautions must be taken during the welding process. For example, the welder must have the right equipment and safety gear, and must follow the appropriate safety procedures. The welder must also use the right welding technique, and the welding parameters must be set correctly. Additionally, the welding area must be adequately ventilated, and the weld must be inspected regularly to ensure that it meets all the objectives.

Choosing the Right Welding Process

When selecting the right welding process for a particular application, the welder must consider the type of material to be joined, the size and thickness of the material, the desired strength of the weld, and the environmental conditions in which the weld will be used. For example, if the weld will be exposed to extreme temperatures, then a process such as gas tungsten arc welding (GTAW) may be more suitable than shielded metal arc welding (SMAW).

Welding Parameters

The welding parameters must be set correctly in order to ensure that the weld is of good quality. The parameters typically include the type of welding process, the welding current, the welding voltage, the welding speed, and the type of welding electrode. The welding current, voltage, and speed must be adjusted according to the type of material being joined and the size and thickness of the material.

Welding Inspections

Regular inspections of the weld are also important to ensure that it meets all the objectives. The weld must be visually inspected for cracks, blemishes, or other defects. The weld must also be tested for strength and integrity. The type of test used will depend on the type of weld and the material being joined.


Arc welding is a popular and cost-effective welding process that is used in many industries. In order to ensure that the weld is of good quality, certain objectives must be met. These objectives include creating a strong and reliable joint, withstanding environmental conditions, being cost effective and efficient, being of good quality, being strong enough to resist external forces, being aesthetically pleasing, and being safe. The right welding process and welding parameters must be chosen, and the weld must be regularly inspected to ensure that it meets all the objectives.
