Square Groove Weld: What, Symbol, Diagram,Process, Machine, Strength and Several Facts

In this article, “Square groove weld” and square groove weld related several facts such as Symbol, Diagram, Process, Machine, and Strength will be discussed. Square groove weld is a type of Butt Welding Joint.

The limitation of the Square groove weld is the thickness of the joints. By the help of Square groove weld welders are creating joints in between one edge joint to another edges joints, although Square groove weld is also used to joints the corners, joints of the T and also joining the flat and curved pieces.

What is a square groove weld?

The work mechanism for the square groove weld is not very complicated and unskilled welder easily can work with the process of the square groove weld.

The square groove weld can be define as, it is the classification of the butt welding joint where two parallel and flat pieces are joint to each other. By the help of square groove weld a certain amount of strength can be provide to the joints. Joint thickness of the square groove weld is not so versatile.

Advantages:-

The advantages of the square groove weld are listed below,

  1. Inspection process with the square groove weld is easy. Easily defect can be identifying.
  2. Working mechanism square groove weld is not too much complicated.
  3. Economical to use.
  4. Distortion control is good for the square groove weld.
  5. Strength of the square groove weld is high.
  6. Penetration rate of square groove weld is too high almost 100%.
  7. Provide complete fusion.
  8. Stress produce by the square groove weld is very less.

Disadvantages:-

The disadvantages of the square groove weld are listed below,

  1. Geometrical application for the square groove weld is limited.
  2. With the weekly products like products of electronics cannot be work with the square groove weld.
  3. Not self aligning. When welders work with the square groove weld backer or fixturing is required.
  4. Impressionable to faying area condition.

Square groove weld symbol:

The groove of any square groove weld is made by the little amount of detachment of the margin or a tight fit. The weld symbol for the square groove weld is defining the total volume of detachment.

Square groove weld symbol is given below,

Square groove weld size:

The square groove weld is the term of the American National Standards Institute and butt weld is the term of the International Organization for Standardization.

The indication for the size of the square groove weld is the effective throat. The depth for the square groove easily can be defined by the size and also the penetration rate into the roots of the joints.

The term square groove weld and butt welds is the same classification of the weld.

Square groove weld strength:

The square groove weld is used to weld cheap and simple welding joints. In the sheet metal which thickness is less than the 5 mm in that case the square groove weld is used.

The strength of the square groove weld is depend upon some factors which are listed below,

Square groove weld example:

The examples of the square groove weld is listed below,

  • Metalworking magazine
  • Fabricating magazine
  • Construction of bridges

Frequent Asked Questions:-

Question: – Classify the types of the welding process.

Solution: – The process of welding we can classify in 9 categorised. The classification of the process of welding are listed below,

  • Tungsten Insert Gas Welding Process
  • Metal Insert Gas Welding Process
  • Thermic Welding Process
  • Forge Welding Process
  • Flux Cored Arc Welding Process
  • Resistance Welding Process
  • Stick Shield Metal Arc Welding Process
  • Submerged Welding Process
  • Oxyacetane Welding Process

Question: – Briefly describe any two types of the welding process.

Solution: – Two types of welding process is listed below,

Tungsten Insert Gas Welding Process:-

Another name for the Tungsten Insert Gas Welding process is Gas Tungsten Arc Welding process. In the Tungsten Insert Gas Welding process electrode which is made tungsten is used and the electrode should be non – consumable type to create weld.

The area of weld and electrode both are out of hazard from atmospheric contamination and oxidation with help of insert shielding gas. The shielding gas that could be use in the Tungsten Insert Gas Welding process is Helium and Argon.

The base metals which can be work with Tungsten Insert Gas Welding process are, Aluminium and alloys of aluminium, carbon steel and alloys of carbon steel, stainless steel.

Advantages:-

The advantages of the Tungsten Insert Gas Welding process are listed below,

  1. Tungsten Insert Gas welding process is clean.
  2. High quality weld can be making with Tungsten Insert Gas welding process.
  3. Smoke is not produce.
  4. A huge range of materials can be weld with the Tungsten Insert Gas welding process.
  5. Almost in every position Tungsten Insert Gas Welding process can be work.

Disadvantages:-

The disadvantages of the Tungsten Insert Gas Welding process are listed below,

  1. Deposition rate of the Tungsten Insert Gas Welding process is low.
  2. Skilled operators are needed to operate Tungsten Insert Gas Welding process.
  3. Speed of the welding is not too fast.
  4. Non automation.
  5. Initial cost of the Tungsten Insert Gas Welding process is high.

Metal Insert Gas Welding Process:-

Metal insert gas welding process an example of arc welding method. In the Metal Insert Gas Welding process electrode which is used should be consumable type to create weld. The two base metals are joined with each other by the help of Metal insert gas welding process. In the Metal insert gas Welding method the equipments which are used are listed below,

  • 1. Welding power supply
  • 2. Welding torch
  • 3. Wire feed unit
  • 4. Shielding gas supply
  • 5. Welding electrode wire

  3. For the outside welding Metal insert gas welding process is not appropriate.

Question: – What is the advantage of using the square groove joint?

Solution: – With V-groove welds, the edges of both pieces are chamfered, either singly or doubly, to create the groove.

Each type of joint has its advantages and disadvantages, but the biggest advantage of the butt joint and square groove joint is its strength. It can withstand stress better than any other type of joint design.

Question: – Write down the difference between the groove weld and fillet weld.

Solution: – The difference between the groove weld and fillet weld is,

Fillet weld = A weld of nearly triangular cross section joining two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint.

Groove Weld = A weld made in a groove between the workpieces.
