let QUEST-TECH help you with your next project
Quest-Tech is proud to offer advanced welding services for stainless steel, aluminum, carbon steel along with other metals. Quest-Tech utilizes a variety of methods to meet fabrication requirements of our customers. Our welders have a wide range of ASME certifications to ensure that we are able to meet customers’ expectations. We have 8 MIG welding stations, each set-up for production welding utilizing state-of-the-art industrial equipment and fixturing tables.
Quest-Tech’s certified welders are trained in welding processes for a variety of industrial components such as oil and gas processing equipment, fabricated sheet metal cabinetry, food and medical grade stainless steel, installation of hardware and much more.
The Basics of Welding
Welding of metals is a highly specialized process that employs heat and filler metal to join two or more pieces of metal, permanently bonding them together. The process is used across a variety of industrial and production sectors globally, including aerospace, transportation (such as trains, rail carriages, and automobiles), energy transport, medical instruments and supplies, food and beverage equipment, nuclear equipment, and a whole range of other industries.
There are close to 30 types of welding processes, using such elements as gas, electricity, and lasers; formed by hand, machine, or robotics. The three methods we utilize are:
MIG welding is used in most types of fabrication and for maintenance and repair welding. MIG stands for metal inert gas but is short for its technical name, Gas Metal Arc Welding (GMAW). It is also a versatile welding method that provides a clean finish on a variety of metals and alloys like steel, aluminum, stainless steel, and carbon steel. It can be used to weld very thin gauge material. MIG welding offers high productivity, makes for great-looking weld finishes, can be welded in all positions, and very little cleanup.
Quest-Tech utilizes Miller 350P Pulsed-MIG technology. The Millermatic 350P provides more arc power and improves productivity relative to its peers. MIG welding applications are used in such industries as automotive, construction, plumbing, robotics, and maritime.
TIG welding is a popular choice as it can produce superior weld quality, generally free of defects. TIG stands for tungsten inert gas but is the technical name for Gas Tungsten Arc Welding (GTAW). The method joins metals by heating them with an arc between a tungsten electrode (non-consumable) and the workpiece.
TIG is ideal for welding critical joints where small or exceptionally precise welds are required. The result is a high-quality and high-purity weld. Like MIG welding, TIG welding is versatile and can be performed on a wide variety of metals and alloys. It is common in such industries as aerospace, automotive, motorcycle and bike manufacturing, tubing and wherever high precision welds are required. Quest-Tech utilizes Canox, Memco, and Hobart technology for its TIG welding jobs.
Stick welding, sometimes referred to as arc welding, is the most widely used of the various arc welding processes. It is an extremely versatile process, too, and is suitable for most of the commonly used metals and alloys. Stick welding is used on heavy metals of size 4mm and above. Its application is best suited for repairing and fabricating heavy equipment, steel erection, and pipeline welding, as well as in the manufacturing and construction industries.
Quest-Tech offers a wide selection of welding services, including pipe welding. We are capable of handling any of your low-pressure pipe assemblies, joining and repairing tubular products, and metallic pipe components and assemblies to meet customer needs.
Quest-Tech can weld pipe from as small in diameter as 1 inch and larger. We are equipped with 2 overhead cranes to assist in welding heavier gauge material, and a third jib crane to assist operators with heavier items and assist in forming. 3 TIG stations are set up for production of stainless and aluminum material where needed.
Spot Welding & Weld Nuts
Quest-Tech offers industrial spot welding, an extremely versatile welding application that produces strong joints through high pressure in a relatively small area. It is used where a substantial amount of weld energy is required along with a fine range. Weld energy is produced through electrical current and can be increased incrementally when needed. We have 2 spot welders for up to 1/8” aluminum.
Quest-Tech also offers weld nut fastening for our customer with the usage of the 2 spot welders. Weld nuts can be incorporated onto the surface of stainless steel, carbon steel, aluminum as well as other metals to provide a permanent threaded feature on your finished parts to be able to be used for standard fasteners.
Stud welding joins a metal stud to a metal workpiece and is used in everything from kitchen appliances to the building of bridge decks and construction of tankers and military ships. Quest-Tech offers stud welding for applications used in the manufacturing of stainless steel components, with capability up to 3/4 inch (19mm) studs of various lengths and for standalone machines.
