Metal is an essential part of modern life because of its malleability, strength, and appearance. Structural steel is used to support buildings, and stainless steel to make elegant railings and gates. Metals can cope with the high stresses and temperatures found in engines and machinery and can shrug off the elements. However, as with anything, metals eventually fail. Corrosion weakens steel, while wear and tear cause parts to break.
Improvements in the efficiency and productivity of welding technologies have made it easier to repair these metal components instead of the more expensive choice of replacing them. If you want a reliable welding repair in Sydney, how do you find someone qualified and professional?
A skilled welder understands the nuances of metals and knows what it takes to make a strong and effective repair. They can cut out damaged or corroded metal, joining pieces and repairing the surface to leave it smooth and even.
Repairs can stop the rot
As anyone who works with metal will tell you, corrosion is your enemy. Any damage to metal, whether a dent or break, lets the rust in, weakening it even further. Even painting over damage only covers rust, and the metal will keep on deteriorating.
Over time, the damage spreads, meaning more expense when it inevitably fails. In a worst-case scenario, the metal may become non-repairable with no sound surface that the welder can use to make the weld.
A small repair now can save a lot of time and money in the future, and help you avoid severe consequences for critical parts and structural steel where failure is not an option. Welders should also ideally understand the importance of cleaning metal before joining to make sure the problem doesn’t reappear. On-site welding often includes repairs to structures and buildings to keep them in service.
Steel and aluminium repairs
Naturally, welders have to repair a range of metals, including aluminium and stainless steel, structural steel, and hardened steel. The approach for each is customised to suit the individual project, making sure that the weld withstands the stresses and strains of time and does not become a weak point.
For example, aluminium is always a difficult weld, especially once it has been in service where dirt and oxidation make bonding difficult. To complicate the process, aluminium is delicate and careless welding can cause burn-through or deformation. Only welders familiar with the unique properties of aluminium will be able to work with the metal and leave a strong, enduring weld.

MIG or TIG: Which is Best?
The first thing welders decide during a repair is the right welding technique to use. MIG welding is excellent for repair work because it is quick and efficient. Using MIG, welders can get you up and running quickly, minimising downtime.
TIG welding takes longer and requires more skill, but it is an excellent technique for precision work. Because TIG torches are smaller, they are better for constricted and difficult to reach areas. TIG is also useful for aluminium because it produces less heat and less chance of burn through.
Conclusion
Ultimately, once you make a repair, you don’t want to revisit it. A porous weld is weak and lets water ingress to wreak havoc. The tried-and-tested Sydney Welders philosophy means we never compromise on quality at competitive prices.
Consistent thickness and smooth surface are also important for adding strength and for aesthetics, especially for visible joins on railings, vehicle bodywork, and catering equipment. Our welders take such pride in their work that they leave smooth, clean welds even when out of sight to avoid leaving potential faults.
Over the years, we have earned a reputation for high-quality repairs, through our mobile service or at our fabrication shops. Whether you need to repair heavy machinery, patch a vehicle, or revitalise stairways and railings in your home or business, give us a call on 02 8074 3446.
