Sheet Metal Welding Service

Precision Welding Process

There are five basic steps to precision welding, no matter your welding process.Below is a stepwise procedure on how we generally function:

  • First, we prepare the aluminum or stainless steel tubes by cutting, smoothing edges, punching holes or stamping based on the client’s specifications.
  • The metal tube then goes to the robot welding line. Of the many welding processes, robotic welding is highly accurate, enhances safety and reduces production time.
  • Once the component is complete, it goes to quality inspection where 5 out of 100 parts are tested. If one problem is found, the whole batch is inspected to ensure they meet the required tolerance.
  • Molten metal is highly malleable. Some aluminum frames require heat treatment due to deformation that occurs when the welding device creates excessive heat.
  • The components are shipped to an assembly plant. We deliver automotive and powersports frames fully painted and coated, with the quality of having a mirror effect.

As a rule of thumb, welders should measure twice and cut once. In some cases, you may need to redesign joints to have higher heat resistance.

What Is Welding Process

What Is Welding Process

Welding is a process of joining two or more pieces of metal or thermoplastics together by applying heat, pressure, or both. The welding process involves the localized melting and fusion of the materials to form a strong bond. It is widely used in various industries, including manufacturing, construction, automotive, aerospace, and more.Welding plays a crucial role in numerous industries, contributing to the construction of infrastructure, manufacturing of machinery and equipment, and the production of consumer goods.

How Does Welding Work?

Welding works by joining two or more pieces of metal or thermoplastics together through the application of heat, pressure, or both. The welding process involves several key steps:

Preparation: Before welding, the materials to be joined need to be prepared. This may involve cleaning the surfaces to remove any dirt, rust, or contaminants that could interfere with the welding process. The edges of the materials may also be shaped or prepared to create a suitable joint configuration.
Heat Generation: The heat required for welding can be generated through various methods, depending on the welding process used. For example, in arc welding, an electric arc is created between the electrode and the workpiece, generating intense heat. In gas welding, a flame produced by burning fuel gases mixed with oxygen provides the heat. Other processes such as laser welding or electron beam welding use highly concentrated energy sources to generate heat.
Melting and Fusion: The intense heat generated during welding causes the base metals or thermoplastics to reach their melting points. In the case of metals, the heat causes the base metal to melt along with the filler material (if used), creating a molten pool. The molten metal or thermoplastic fills the joint area, allowing for fusion and bonding between the materials.
Filler Material (if applicable): In some welding processes, a filler material is added to the joint to enhance strength or fill gaps. The filler material, usually in the form of a rod or wire, is melted and added to the molten pool to reinforce the joint.
Solidification: Once the welding heat source is removed, the molten pool cools and solidifies, forming a solid joint between the materials. During solidification, the molten material undergoes a phase change and solidifies into a solid metal or thermoplastic bond.
Post-Weld Treatment: Depending on the specific requirements of the welded joint, post-weld treatments may be performed. This can include processes such as grinding, cleaning, or heat treatment to remove any welding defects, improve the appearance, or enhance the strength and durability of the joint.

Different Types of Welding and Their Uses

There are several different types of welding processes, each with its own characteristics and applications. Here are some common types of welding and their uses:

Shielded Metal Arc Welding (SMAW)

Also known as Stick welding, SMAW involves using a consumable electrode covered in flux. It is a versatile welding method and is widely used in construction, maintenance, and repair work, as well as in pipelines and structural steel fabrication.

Gas Metal Arc Welding (GMAW) or Metal Inert Gas (MIG) Welding

GMAW uses a consumable wire electrode and a shielding gas, typically a mixture of argon and carbon dioxide. It is commonly used in manufacturing, automotive, and fabrication industries for welding thin to medium-thickness materials.

Flux-Cored Arc Welding (FCAW)

FCAW is similar to GMAW, but it uses a tubular wire electrode filled with flux instead of a solid wire. It is known for its high deposition rates and is often used in heavy fabrication, shipbuilding, and structural steel applications.

Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) Welding

GTAW uses a non-consumable tungsten electrode and an inert gas, such as argon, for shielding. It is known for its high-quality welds and precise control, making it suitable for aerospace, automotive, and nuclear industries, as well as for welding thin materials and exotic metals.

Submerged Arc Welding (SAW)

SAW involves feeding a continuous wire electrode into the joint while covering it with a granular flux. It is primarily used for welding thick materials in heavy fabrication, pressure vessel manufacturing, and pipe welding applications.

Resistance Spot Welding (RSW)

RSW uses electrodes to clamp and apply pressure to the joint area, passing an electric current through it. It is commonly used in the automotive industry for joining sheet metal components, such as body panels.

Electron Beam Welding (EBW)

EBW utilizes a highly focused beam of electrons to generate heat and create welds. It is used for joining high-strength materials, critical aerospace components, and precision welding applications.

Laser Beam Welding (LBW)

LBW uses a highly concentrated laser beam to generate heat and create welds. It is suitable for precision welding of thin materials, medical devices, electronics, and automotive components.

Friction Stir Welding (FSW)

FSW involves using a rotating tool to create friction and heat, joining materials without fully melting them. It is used for joining aluminum and other non-ferrous materials, particularly in the aerospace and automotive industries.
