The Benefits of Welding

Joinability: Welding creates strong and durable joints between components, enabling the fabrication of complex structures and assemblies.

Strength and Durability: Welded joints typically have high strength and durability. The fusion of the base materials during welding creates a permanent bond that can withstand enormous stress, vibration and pressure.

Efficiency and cost-effectiveness: Welding is an efficient and cost-effective joining method, especially in high-volume production or repairs.

Design Flexibility: Welding provides design flexibility and allows for the creation of complex and custom structures.

Repair and maintenance: Welding plays an important role in repair and maintenance operations, restoring damaged or worn components to their original condition.

Low Carbon Steel Welding

Low Carbon Steel Welding

For low carbon steel welding, we need to care about the consistent welding bead, the deformation after welding, and the welding bead size to make sure of strength. We usually use Tig welding for the thin steel sheet or steel pipe, and Mig welding for thick steel sheet. Removing cleanly the welding spatters to make sure of fine finish. We are equipped with welding station at 2000*4000mm that enables us to weld big steel structures or frames.

 

Stainless Steel Welding

Stainless welding, Tig welding is the frequently used option with stainless welding wire. We have much experience in handling Stainless steel products welding, knowing how to control the welding speed to form the good looking welding bead, and the electrical currency to make sure of the welding strength.

Besides, in order to make sure of the welding precision, we are designing and building the welding fixture to allocate all the welded components in correct place, and control the welded frame or structures at the correct size.

Stainless Steel Welding
Aluminum Welding

Aluminum Welding

Compare with Carbon steel or Stainless Steel, apparently Aluminum ally is the most difficult material to weld, as it is much affected by the workshop enverionment like humidity or tempreture.

We are normally use tig welding for all the aluminum welded parts, and we have the welding operators who are handling the aluminum welding exclusively, and our aluminum welding areas are seperated to avoid contamination from the stainless steel or carbon steel.

The Resource About Welding

Welding is an essential construction-related activity that is typically used to bring materials together through the application of heat. It is a manufacturing process that involves the use of heat, pressure or both to fuse two parts.

Although the definiations of Welding make it sound simple, welding is far from easy. Consider some of the basic principles of welding.

  • Welding involves a high level of skill and plastical knowledge of the disciplines of physics, chemistry and metallurgy.
  • Generally, welding is performed on metal, but it also used to fuse wood or themoplastic parts.
  • Different metals react in different ways, depending on their physical, mechanical and chemical properties.

Advanced Welded Assemblies by Gmetal

At Gmetal, we specialize in welded assemblies, a sophisticated metal construction technique. By fusing various metals like stainless steel, we craft complex structures tailored to unique applications. Our expertise spans from crafting small components like brackets to larger parts such as tubes, demonstrating our versatility in welding assembly.

Understanding Welding: A Guide to the Parts of Welds

In welding, it’s crucial to be familiar with the various components that make up different types of welds. This knowledge is fundamental for every welder.

  • Components of Weld Diagrams
  1. Parts of a Fillet Weld: This type of weld joins two pieces of metal, either at an angle (typically 60 to 120 degrees) or at lapped flat ends. The bead of the weld is located on the inner corner formed by the base metal.
  2. Parts of a Groove Weld: A groove weld consists of a bead positioned within a groove on the workpiece surface or in the gap between two butted pieces.
  • Detailed Explanation of Weld Parts

Weld Toe: The point where the weld face meets the base metal.

Weld Face: The visible surface of the weld on the side where the torch created the weld.

Weld Root: Located at the opposite end of the weld face, it is where the weld and base metal meet at the bottom of the weld.

Weld Leg: The measurement from the weld toe to the weld root.

Fusion Zone: The area of base metal that has melted during the welding process, identifiable in a cross-section.

Weld Reinforcement: The height of the weld portion that extends above the base metal surface.

Fillet Weld Throat: In a fillet weld, the theoretical throat is the distance from the largest right triangle’s hypotenuse, inscribed within the fillet weld cross-section, to the root. The actual throat is the distance from the fillet weld’s root to the center of its face.

  • Determining the Size of the Weld
  1. Equal Leg Length Fillet Welds: The size is determined by the leg length of the largest isosceles right triangle that fits within the fillet weld cross-section.
  2. Unequal Leg Length Fillet Welds: The size is defined by the length of the largest leg of the largest right triangle that can be inscribed within the fillet weld cross-section.
  3. Groove Welds: The size of a groove weld is indicated by the depth of chamfering plus the root penetration, when specified.

This comprehensive understanding of the various parts of welds is essential for precision and effectiveness in welding tasks.
