Welding Equipment
Laser Processing Equipment: How to Avoid Burn-Through When Welding Thin-Walled Materials
For buyers of laser processing equipment, preventing burn-through on thin-walled materials is a top concern during welding. This issue often stems from excessive heat input, but with proper equipment settings and techniques, it can be effectively avoided.
Optimize Laser Processing Equipment Parameters
The core solution lies in adjusting key parameters of laser processing equipment. Lower the laser power appropriately and increase the welding speed to reduce the heat contact time between the beam and the material. Pulsed laser mode is more suitable than continuous wave mode here—it delivers energy in short bursts, limiting heat accumulation and minimizing the risk of burn-through.
Adopt Suitable Welding Aids and Techniques
Using filler wires matching the base material adds thickness to the weld seam, which helps distribute heat evenly. Additionally, laser processing equipment equipped with gas nozzles can blow inert gas (such as argon) to protect the weld pool, reducing oxidation and stabilizing the welding process. Fixtures with good thermal conductivity can also dissipate excess heat quickly.
Key Buying Tips
When selecting laser processing equipment, prioritize models with flexible parameter adjustment and pulse waveform customization. These features allow precise control over heat input, which is critical for thin-walled material welding.
By combining the right equipment settings with auxiliary methods, laser processing equipment can achieve high-quality welds on thin-walled materials without burn-through issues.
Choose Haiwei Laser’s laser welders—flexible parameter tuning and stable performance prevent thin-walled material burn-through effectively.

How Do Laser Welding Machines Reduce Welding Thermal Stress?
Thermal stress from welding can cause material deformation or cracks, a key concern for buyers choosing laser welding machines. The good news is that modern laser welding machines offer practical ways to minimize this issue through targeted settings and techniques.
Optimize Laser Parameters
Adjusting core parameters of the laser welding machine is the first step. Lowering heat input by fine-tuning power and increasing welding speed reduces the time materials are exposed to high temperatures. Pulsed laser modes, rather than continuous wave, deliver energy in controlled bursts, limiting heat spread and stress buildup—ideal for thin or heat-sensitive metals.
Choose Suitable Welding Techniques
Laser welding machines support techniques like seam tracking and wobble welding that cut down stress. Seam tracking ensures the laser follows the joint precisely, avoiding unnecessary heat application. Wobble welding distributes energy evenly across the weld area, preventing localized overheating and uneven stress distribution.
Use Auxiliary Cooling and Material Prep
Pairing the laser welding machine with simple cooling solutions (like forced air or water cooling) helps dissipate heat faster. Additionally, preheating materials moderately (for thicker workpieces) or cleaning surfaces to remove contaminants ensures more uniform heat absorption, reducing stress concentration.
When selecting a laser welding machine, prioritize models with flexible parameter adjustment and compatible technique support. These features let you tailor operations to your materials, minimizing thermal stress and ensuring consistent, high-quality welds for your production needs.
For reliable thermal stress reduction, choose Haiwei Laser’s laser welders—precision controls and optimized tech deliver consistent, high-quality welds.

Why Laser Welding Machines Enable Energy Saving and Emission Reduction in Welding
As sustainability becomes a top priority for manufacturers, many are curious why laser welding machines stand out for energy efficiency and low emissions. Unlike traditional welding methods, these devices are engineered to minimize waste—making them a smart choice for both cost savings and environmental goals.
Precise Energy Delivery Cuts Waste
The biggest reason laser welding machines save energy is their targeted energy application. Traditional arc welding runs at high power continuously, even during idle moments, wasting significant electricity. A laser welding machine only activates its laser when directly welding the joint, focusing energy into a tiny spot. This means less energy is lost to heat dissipation or unused output. For example, welding 2mm steel sheets typically uses 30–40% less energy than MIG welding, based on common factory operations.
Design Features That Reduce Emissions
Laser welding machines also lower emissions through thoughtful design:
Minimal consumables: Unlike methods needing welding wire or flux, laser welding uses little to no extra materials, reducing waste from production and disposal.
Reduced fumes and slag: The concentrated heat creates fewer fumes and almost no slag, cutting down on air pollutants and the energy needed for cleanup.
Efficient cooling: Modern laser welding machines have optimized cooling systems that use less power than the large chillers required for traditional welding.
What Buyers Should Know
When choosing a laser welding machine, look for models with adaptive power control—this feature adjusts energy output based on material thickness, avoiding over-welding. Also, check for energy consumption data in the specifications to compare efficiency across options.
A laser welding machine isn’t just a precision tool; it’s an investment in sustainable production. The energy and emission savings add up over time, lowering operating costs while supporting environmental standards.
For sustainable, efficient welding, choose Haiwei Laser’s laser welding machine—engineered for energy savings and low emissions to support your production goals.

Laser Welding Machine: Meeting Hermetic Sealing Requirements
For industries like aerospace, medical devices, and automotive electronics, hermetic (airtight) welding is a critical requirement to protect internal components from moisture, dust, and gas leakage. A well-engineered laser welding machine can reliably achieve this standard, addressing a core pain point for buyers seeking consistent, high-quality sealing solutions.
How a Laser Welding Machine Ensures Airtightness
The key to hermetic welding lies in creating a fully fused, defect-free weld seam. A quality laser welding machine delivers concentrated, controlled heat input that melts metal uniformly without creating pores, cracks, or incomplete fusion—common flaws that cause leaks. Its narrow heat-affected zone (HAZ) also minimizes workpiece distortion, which is essential for maintaining the structural integrity of sealed enclosures like sensor housings or battery packs. Additionally, integrated coaxial gas shielding displaces air during welding, preventing oxidation that could weaken seam tightness.
Key Considerations for Buyers
When selecting a laser welding machine for hermetic applications, prioritize models with stable beam quality and adjustable pulse parameters to match your material thickness and type. Request leak-test reports for sample welds, and verify that the equipment supports precision motion control (e.g., 4-axis systems) to handle complex enclosure geometries. These features ensure the machine can consistently meet your airtight welding demands.
For reliable hermetic sealing that complies with industry standards, a high-performance laser welding machine is a smart investment for long-term production quality.
