Five Most Common Questions We Get at Overseas Exhibitions

As a professional manufacturer focusing on laser equipment R&D and production, SFX Laser participates in several international exhibitions every year. These exhibitions are not only an excellent opportunity to showcase the latest laser cleaning machines and laser welding machines, but also a chance to meet global customers face to face.

For many visitors, it’s their very first time to see fiber laser cleaning or laser welding equipment up close, so naturally, they have plenty of questions. Interestingly, we’ve found that customers’ concerns are often very similar. To help more people online quickly get answers, we’ve summarized the five most frequently asked questions at exhibitions and provided our professional responses.

Question 1: What materials can a Laser Cleaning Machine clean?

This is by far the most common question we receive.

The advantage of an SFX Laser Cleaning Machine is that it can be applied to almost all types of metal surfaces. Whether it’s steel, iron, stainless steel, or aluminum, the laser can efficiently remove rust, oxide layers, oil stains, and paint coatings.

Beyond metals, laser cleaning can also handle certain coatings on non-metal surfaces, making it highly versatile.

Typical application scenarios include:

  • Industrial parts rust removal (gears, molds, pipelines)
  • Surface treatment in the automotive industry
  • Pre- and post-welding cleaning of workpieces
  • Maintenance of ships and aerospace equipment
  • Cultural relic restoration and stone surface cleaning

Compared with traditional chemical cleaning or sandblasting, fiber laser cleaning machines are more eco-friendly, require no consumables, and deliver higher efficiency.

Question 2: What advantages does a Laser Welding Machine have over traditional welding?

When visitors see an SFX Laser Welding Machine for the first time, they often ask how it differs from TIG or manual welding.

Our answer is simple: the efficiency and quality are on a whole new level.

Main advantages:

  • High welding efficiency – up to 3–8 times faster than traditional welding
  • Beautiful weld seams – smooth, uniform, requiring little or no grinding
  • Easy to operate – beginners can master it after short training
  • Wide material compatibility – stainless steel, carbon steel, aluminum alloy, galvanized sheets, and more
  • Cost reduction – less manpower, less rework

That’s why fiber laser welding machines are especially suitable for industries with high efficiency and aesthetics demands, such as kitchenware, auto parts, and metal furniture manufacturing.

Question 3: How to choose the right machine power?

Another common exhibition question is: “What’s the difference between a 200W laser cleaning machine and a 1000W one? Which should I choose?”

The answer depends on your specific needs:

Laser Cleaning Machines

  • 300W–500W → Suitable for small workpieces or fine cleaning (molds, precision parts)
  • 1500W/2000W/3000W → Ideal for large-area rust removal (ship hulls, steel structures, pipelines)

Laser Welding Machines

  • 1500W → Perfect for 1–6mm thickness sheet metal
  • 2000W/3000W → Suitable for thicker materials and continuous welding

At SFX Laser, we always recommend the right laser cleaning or welding equipment based on your industry, material type, and workpiece size to avoid underpowering or overspending.

Question 4: What about after-sales service and training?

For many customers, the biggest concern after purchasing a laser machine is whether they can operate it smoothly and get fast support when issues arise.

Our approach:

  • Operation training – detailed video tutorials and manuals, easy for beginners
  • Remote support – one-on-one guidance via video call or remote connection
  • After-sales guarantee – a dedicated service team and exclusive communication channels
  • Hands-on experience at exhibitions – customers can try the machines on-site

We always emphasize: buying the machine is just the first step, reliable service ensures long-term success.

Question 5: How about shipping and warranty?

Another common worry is: “The equipment is so large, will international shipping be complicated?”

Our answer: no need to worry.

  • Shipping solutions – sea freight, air freight, express delivery; plus, we stock popular models in our U.S. and European warehouses for faster delivery
  • Warranty – 1-year warranty for the whole machine, 2 years for the laser source
  • Spare parts support – ready-to-ship accessories, no long waiting times

This ensures customers worldwide can buy and use SFX Laser Cleaning and Welding Machines with confidence.

Conclusion

The questions asked at exhibitions reflect the most genuine concerns of potential buyers: machine performance, application scope, ease of operation, after-sales service, and delivery. At SFX Laser, these concerns drive us to continuously improve our Laser Cleaning Machines, Fiber Laser Welding Machines, and industrial laser solutions.
