About Us

Hotspot Providing High Quality Services

Hotspot Welding Ltd was established in 2018 as a family business by a father and son team, namely Gideon & Charl Brummer. The main protagonist and driving force in the Company is Gideon Brummer, who has over 30 years of experience in the industry.

We are situated in Silverdale. During our few years in this business, we have gained a wealth of experience with regards to the handling of general steel services like Structural Steel, General Steel Fabrication, Trailer manufacturing & repairs and more so, the core of our business, light fabrication and production welding.

Our vision, as a company, keeping quality and service at the forefront, is to become the preferred supplier of fabricated steel and production welded components to companies like yourself, who represent big business in New Zealand. This would eventually translate into us improving our standard of life, the standard of life of our people, and on a bigger scale, the standard of life of the communities which we live in, and the communities which surround us.

Our business is contract driven, and we are proud to say that, in the face of strong competition we have successfully completed many contracts in the past. We have achieved these milestones not on our own, but because of the active contributions made by our staff. We admire the drive and commitment in our people and we try as far as possible to reward their contribution to our success as a business.

We are a small emerging enterprise, with a drive to succeed, and we rely strongly on your support and we are sure that by supporting us, you will also be directly supporting our vision, and ultimately contributing towards a better New Zealand.

Frequently Asked Questions

What Is Stick Welding?

Shielded Metal Arc Welding, commonly called Stick, is a welding process that uses an electrode (welding rod) to carry the electric current and provide the majority of the weld metal. The electrode consists of a core wire coated in flux. An electric arc is created across the gap when the energized circuit and the electrode tip touches the work piece and is withdrawn, yet still within close contact, generating temperatures of approximately 6500°F. This heat melts both the base metal and the electrode creating the weld. During this process, the molten metal is protected from oxides and nitrides in the atmosphere by a gaseous shield created by the vaporizing of the flux coating. The electrode produces a slag covering on the finished weld.
Typical Uses: Steel Erection, Heavy Equipment Repair, Construction, Pipeline Welding

What Is TIG Welding?

Gas Tungsten Arc Welding, commonly called TIG or Heliarc, is a welding process that uses a non-consumable tungsten electrode to heat the base metal and to create a molten weld puddle. An autogenous (no filler metal) weld can be created by melting two pieces of metal together. An external filler rod can be added into the molten puddle to create the weld bead and increase mechanical properties. Like the GMAW process, the molten weld puddle needs to be shielded by an external gas supply. The most commonly used shielding gas is argon, but argon/helium mixtures can be used on heavy aluminum. GTAW can be used to weld most alloys.
Typical Uses: Aerospace welding, piping systems, vehicles, motorcycles or bikes

What Is MIG Welding?

Gas Metal Arc Welding, commonly called MIG welding, is a process that uses a continuously fed, solid wire electrode through a welding “gun.” The operator pulls a trigger on the welding gun, which feeds the consumable electrode through. An electric arc forms between the electrode and the base material, which heats the base material, causing it to melt, and join. The molten weld metal is protected from oxides and nitrides in the atmosphere by an externally supplied shielding gas. The most commonly used gas is carbon dioxide or a mixture of argon and carbon dioxide. The GMAW process can be used to weld a wide range of alloys including carbon steel, stainless steel, magnesium, nickel, copper, silicon bronze and aluminum.
Typical Uses: Small to Large Manufacturing, Auto Body, Fabrication

What Is Arc Welding?

Flux-cored Arc Welding is a welding process similar to GMAW, in that it uses a continuously fed electrode, but uses a tubular wire filled with flux instead of a solid wire. There are two types of flux-cored wire, self-shielded and dual shield. Self-shielded is used without the aid of an external gas shield and uses the flux to shield the molten weld puddle. Dual shield uses the flux and an external shielding gas to protect the molten weld puddle. Typical shielding gases are carbon dioxide and argon/carbon dioxide mixes. Self-shielded wires are optimal for outdoor use, even in windy situations. Both wires produce a slag covering on the finished weld.
Typical Uses: Thick materials, Steel Erection, Heavy Equipment Construction or Repair

How Do You Finish A Weld?

Every welding job’s requirements are different, but we often grind the welds, polish the welds, descale the welds, prepare the welded surfaces for painting, and prime the prepared surface after the welding process is completed—all based on individual customer requirements.
