Laser Welder For 12mm Carbon Steel

Challenges in a laser welder for 12mm carbon steel

The laser welder for 12mm carbon steel falls under the category of industrial-grade medium-to-heavy plate welding. Compared to welding thin plates under 3mm, the difficulty increases exponentially. The challenges involved include the following:

• Thermal Distortion Control: The high heat required for thick-plate welding can easily cause the plates to warp, resulting in high post-welding straightening costs.
• Challenges in Deep Penetration: It is essential to ensure that heat energy reaches the root to avoid lack-of-penetration defects; traditional processes often rely on complex groove preparation.
• Challenges of Double-Sided Bead Formation: Without flipping the workpiece, it is extremely difficult to precisely control the pressure in the molten pool to achieve simultaneous bead formation on both sides.
• Risk of Cold Cracks: Thick plates cool extremely quickly, causing the joint to harden; under residual stress, this can easily lead to structural cracks.
• Filling Large Gaps: Assembly gaps in large workpieces are difficult to avoid, placing extremely high demands on the weld’s coverage width and wire deposition capacity.
• Overall Cost Pressure: Traditional welding incurs high gas costs, consumes large amounts of welding wire, and involves significant labor costs associated with frequent gas cylinder changes.

The real challenge in Laser welder for 12mm carbon steel lies in how to ensure full penetration while simultaneously controlling distortion and reducing the costs associated with groove preparation and gas consumables.

laser welder for 12mm Carbon Steel Solutions

Traditional air laser welding is mostly limited to thin plates and feels powerless when facing heavy workpieces. The Kempson KPS-ALW4000 is an industrial deep penetration laser welder（See also: 4000Wエアレーザー溶接機）. That uses 4000W of powerful energy combined with unique deep molten pool technology to overcome the technical challenges of a laser welder for 12mm carbon steel. It can not only weld through but also complete single-sided welding with natural double-sided forming effects, ensuring the connection strength of thick plates remains extremely stable.

Laser Welder for 12mm Carbon Steel Enters the Gasless Era

• Self-Generated Shielding Gas: Self-developed High-purity Gas Generation System： This air laser welding (gas-free) equipment features a built-in precision gas factory. It utilizes a multi-stage vortex conflict separation and filtration system imported from South Korea to extract and convert inert shielding gas (argon/nitrogen) from the air with a purity of up to 99.99%. During the welding process, the self-produced gas simultaneously isolates oxygen to prevent the weld from oxidizing and turning black. This means you no longer need heavy gas cylinders; simply plug in to start high-quality welding mode.
• Cost Efficiency: Save 30,000 RMB in Gas Costs Annually： A traditional 4000W ハンドヘルドレーザー溶接機 usually requires the continuous consumption of purchased argon gas. Based on an average daily consumption of 1-2 cylinders in the domestic market, daily gas expenses are approximately 100 RMB. After switching to Kempson air laser welding, gas costs drop directly to zero. Long-term operation not only saves the labor cost of moving gas cylinders but also significantly improves production gross margins, making it a hard choice for enterprises to reduce costs and increase efficiency.
