Subtypes: 1018, SPCC
Stainless Steel
Stainless SteelHigh mechanical strength, Thermal, Wear, and Corrosion resistance. Stainless steel is low-cost and can be machined easily. Parts made from Stainless steel are durable and do not lose that strength over time.
Subtypes: 301, 304, 316
Finishing Options
We provide various surface finish options. If your required surface treatment is not listed below, feel free to contact us for more options.
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.

What is the Welding?
Welding is the joining process of metallic parts by using Intense Heat. Although, In some cases, pressure is also used for joining, heat is the most common. It is among the most straightforward techniques to join metal parts to form the desired shape.
Fusion and solid-phase welding are the two main types of welding processes. While solid-phase welding uses pressure and the material in the welding location is not melted, the fusion process uses heat to melt down the material.
Either electricity or gas generates the heat in the fusion welding. Heat unites the parts by developing a melt pool, which might involve adding other metals.
Advantages of welding in manufacturing
- Welding produces permanent and strong joints on a variety of material parts.
- It is economical, environmentally friendly, and not restricted in the factory environment.
- Joints created by welding are light in weight compared to other approaches such as Riveting.
- Highly corrosion resistive & less time consuming
- Capable of producing complex parts and can be used in a difficult position.
Types of Fusion Welding
There are several Fusion welding approaches for different types of materials and produce the joints according to the required specification and applications.
Shields Metal Arc Welding (SMAW) or stick welding use a welding rod to melt the weld position. Since SMAW is a straightforward and low-cost process, it is used in repair, construction, manufacturing & shipbuilding.In comparison, the MIG welding process uses the consumable solid wire electrode and produces a strong joint without risk of environmental contamination. That’s why it is best for outdoor applications and used in Automotive, Construction, and Industrial work.
The TIG welding process creates high-quality, smooth welds in the parts using a non-consumable electrode with a filler rod. It is mainly used in the aerospace and automotive industry. Laser beam welding is one of the most accurate welding, which uses a prolonged photon beam targeted at the welding location. Plasma arc welding welds the components by directing a high-velocity stream of ionized gas (plasma) at the welding spot.
Applications
Welding is the heart of the manufacturing process. It is applicable in the manufacturing of various components in several industries.
- Automotive
- Aerospace
- Defense
- Agriculture
- Jewelry
- Electrical & electronics

Welding FAQ
What are the Material Options for Welding at Prolean?
We have various material options for welding, Cast iron, Carbon Steel, Stainless Steel, Aluminum and its alloys, Copper, Magnesium alloy, Brass, Titanium, and more. Choose whatever you need.
Is the strength of the parts decreased after welding?
The joint strength may be less or more than the parent materials. Still, with the proper welding technique and a professional operator, it can be kept within the parent materials’ strength range. Be at ease; our engineers and operators are qualified to construct the joint, maintaining the strength not lower than the parent material.
What is the working temperature of the welding process?
It depends upon the melting point of the materials to be welded. The material needed to be melted down at the welding position, so the working temperature remained slightly more than the melting point.
Does welding cause heat damage to the workpiece?
Welding may affect the nearby heat zone since the material is melted at the welding position. Still, using our computer-controlled welding machines guarantees no thermal damage or change in the physical or mechanical properties.
What is the welding tolerance I can achieve from Prolean?
We are capable of maintaining a tolerance of ± 0.05 mm at the welding position.
