Finishing Options For Welding Part
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
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.
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.
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.
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.
Smooth machining
Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electro-less Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Nickel plating
Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.
Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
Yellow Chromate conversion coating
A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts
PTFE (Teflon) Coating
The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.
Fine machining
The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.
Laser Cladding
Provides excellent corrosion, wear, and abrasion resistance. Laser Cladding is also effective for treating minor surface imperfections such as cavities, tiny cracks, and rust damage.
Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

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.
