At Turpol Tech Industries, we acknowlge that welding is an integral part of the metal fabrication process. we have experience in various projects in industries like residential, commercial, and heavy construction. Our areas of expertise include MIG welding, TIG welding, and Stick welding.
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.
Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air. The process can be semi-automatic or automatic. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used. There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations.
Originally developed for welding aluminium and other non-ferrous materials in the 1940s, GMAW was soon applied to steels because it provided faster welding time compared to other welding processes. The cost of inert gas limited its use in steels until several years later, when the use of semi-inert gases such as carbon dioxide became common. Further developments during the 1950s and 1960s gave the process more versatility and as a result, it became a highly used industrial process. Today, GMAW is the most common industrial welding process, preferred for its versatility, speed and the relative ease of adapting the process to robotic automation. Unlike welding processes that do not employ a shielding gas, such as shielded metal arc welding, it is rarely used outdoors or in other areas of air volatility. A related process, flux cored arc welding, often does not use a shielding gas, but instead employs an electrode wire that is hollow and filled with flux.
MIG welding done by the expert welders at Turpol Tech Industries can provide quality adhesion, while following certain time constraints for our clients.
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.
GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.
TIG welding is a complex, high-quality type of welding that provides a stronger weld to suit your project’s needs. This technique is often considered more difficult and somewhat more time-intensive, yet yields cleaner, more stable results. TIG welding is one of our specialties. We take great pride in our abilities and are eager to work on your next welding project.
Shielded metal arc welding (SMAW), or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. The workpiece and the electrode melts forming a pool of molten metal (weld pool) that cools to form a joint. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.
Because of the versatility of the process and the simplicity of its equipment and operation, shielded metal arc welding is one of the world’s first and most popular welding processes. It dominates other welding processes in the maintenance and repair industry, and though flux-cored arc welding is growing in popularity, SMAW continues to be used extensively in the construction of heavy steel structures and in industrial fabrication.
The process is used primarily to weld iron and steels (including stainless steel) but aluminium, nickel and copper alloys can also be welded with this method.
At Turpol Tech Industries, we have successfully completed large projects for many of our customers. We ensure that the entire process runs smoothly from beginning to end. We start planning from the initial stages in order to eliminate roadblocks and we know firsthand that our clients put their trust in our company for their projects. We strive to collaborate and take every precaution to earn their trust and their future business and referrals.
Welding is a part of fabrication and we take every job seriously in our business. Few metal fabrication shops in the area can prove their credentials in this industry, but we sign off on every custom metal project we create and we don’t turn it over to our clients unless our seal of approval is on it. When you need a proven company to handle your welding and metal fabrication needs, trust in a company that can show you the work they create. You can see the skills of Turpol Tech Industries welders every time a project has been successfully completed.
Welding, fabrication, and polishing are all services that take skill and experience to handle properly. Don’t make the expensive mistake of sending your project to a shop that claims to do all of these services but can’t verify their credentials. At Turpol Tech Industries, we welcome you to bring us your project. Our clients continually come back to us due to our skills in every aspect of our craft.
