How To Accurately Select The Most Suitable Sheet Metal Laser Cutting Service Based On The Thickness And Material Hardness Of The Sheet Metal?
Knowing a sheet metal laser cutting service helps a lot after you find out what sheet thickness and material characteristics are. Actually, various materials and thicknesses will hardly be through by laser cutting parameters as well as by the resulting effects.
Just grabbing a model without paying attention may bring you quality problems and wastes of money very easily. We offer highly accurate matching solutions based on the very latest 2026 standards.
Laser Cutting Parameter Matching for Common Materials
Carbon Steel and Stainless Steel:
For thoroughly working on Q235 carbon steel 1-12mm, 6-12kW power and oxygen assistance seem to be the perfect set of features to both control the speed and avoid slag formation.On the other hand, for 304 stainless steel 1-8mm, our recommendations are to use 8-12kW power and nitrogen assistance so as to effectively suppress oxidation.
Special Alloys:
For aluminum alloy 1-6mm, 12kW power and nitrogen assistance are our suggestions, while anti-reflection technology being used for the protection of the equipment, for titanium alloy 1-4mm, 12kW power and argon assistance are our advice to help in balancing of energy and preventing thermal deformation.
Key Considerations for Laser Cutting
Highly reflective metals processing:
Mixing anti-reflection technology (back-reflection protection) enabled us to solve the cutting problems of aluminum alloy and copper, so we can continuously cut and avoid breakdown of the equipment.
Parameter adjustment:
It is crucial to change the power and feed speed according to the thickness of the sheet to be cut. For example, if you work with ultra-high strength steel (1-8mm), you will have to decrease the feed speed in order to keep the quality of the cut while also meeting the requirements of the industrial structural components.

Why Is It Necessary To Strictly Control The Heat Affected Zone In Industrial Sheet Metal Fabrication To Ensure Subsequent Welding Strength?
In the field of industrial sheet metal fabrication, the laser cutting stage has a major impact on how the parts will be bent and welded later on. Controlling the heat-affected zone (HAZ), i.e. the small surface layer that is altered by being heated, is critical for weld strength and is something that is commonly neglected.
Potential Hazards of the Heat-Affected Zone
Fiber laser cutting creates a 0.1-0.3mm thick surface layer with different mechanical properties (i.e. a heat affected zone or HAZ) that if uncontrolled can cause:

Too much springback during CNC bending leading to bending accuracy deviations of up to 0.2mm, thus impacting assembly.
Lowering the weld toughness of the structural components that will be welded, thus increasing the chances of microcracks and failure to meet the AWS D1.1 requirements for steel structure welding.
Heat-Affected Zone Control Scheme
<オル>
Parameter Optimization: To limit the HAZ to 0.1mm, reduce energy density and increase cutting speed, which will also keep the weld strength at least 95% of the base metal.
Auxiliary Processing: For very high demand projects, a 0.2mm machining allowance is left for subsequent precision grinding to remove the hardened layer, areas of critical welding are processed by the water jet method to completely eliminate the HAZ.
How Can Professional Industrial Sheet Metal Fabrication Manufacturers Ensure Stable Delivery Time Through Equipment Redundancy?
Stable delivery times are a fundamental customer requirement in industrial sheet metal fabrication. Delivery delays are mainly caused by equipment failures and maintenance downtime. We implement an equipment redundancy strategy to provide a "zero delay" delivery guarantee.
Equipment Redundancy System Construction
Our company has several 12kW laser cutting machines and high pressure water jets of the same specifications to set up an "equipment hot backup" system.
In case a single piece of equipment is broken down or is under maintenance, the production line can be immediately switched and the backup equipment can be running within 10 minutes, thus completely avoiding the downtime and ensuring uninterrupted production.
Auxiliary Measures for Delivery Time Guarantee
We implement a 24/7 lights out production mode, along with an intelligent scheduling system aimed at unattended continuous production, thus not only improving efficiency but also reducing the risks of delivery time. Heavy asset investment is turned into a "zero delay" brand promise, satisfying the requirements of high value procurement.
よくある質問
Q1: What are the achievable tolerances for laser cutting and waterjet cutting in sheet metal processing?
Our fiber laser is capable of achieving a positioning accuracy of 0.1mm (ideal for 1-12mm thin plates). However, precision waterjet cutting can consistently maintain a tolerance of 0.05-0.15mm when working on thick plates.
Q2: Why do you suggest giving fiber laser cutting a higher priority when producing high precision aluminum alloy parts?
By combining fiber laser with our dynamic frequency compensation technology, we have achieved a method of eliminating the issue of the accumulation of slag on aluminum alloys after processing. The processing speed is 5-10 times faster than that of waterjet cutting, resulting in a drastic increase in efficiency and a reduction in costs.
Q3: How does LS Manufacturing ensure the perpendicularity of the cut for ultra thick carbon steel plates exceeding 25mm?
LS Manufacturing's solution to the problem is to utilize a powerful waterjet or a laser head, which is compensated for bevel. By lowering the speed and raising the gas flow, we can guarantee that the bevel angle is kept within 1 therefore fulfilling the requirements of thick plates.
Q4: Does fiber laser cutting change the chemical properties of the edges of stainless steel parts?
In some cases when cutting with oxygen, the metal surface can be oxidized. We usually cut the metal with high pressure nitrogen to protect the metal color naturally and also make it easier to weld without doing any extra work.
Q5: My drawing requires extremely small micro holes. Will waterjet cutting cause chipping?
Waterjet cutting micro holes smaller than 1.5mm may cause chipping. To prevent damage in the weak parts of the material, we advise laser pre-drilling or usage of a complete laser setup.
Q6: When customizing sheet metal parts in bulk, which process can help me obtain a more competitive quote?
For large volume workpieces with thickness less than 10mm, fiber laser cutting has such a high production rate per hour that a price of only 40% higher than waterjet cutting would significantly lower your bulk purchase costs.
Q7: If my parts require mirror polishing, what are the considerations for choosing the cutting process?
It would be best if you consider laser cutting together with our surface finishing procedure so that you can minimize grinding after processing, get a surface roughness of around Ra1.6, and be ready for mirror polishing.
Q8: Will LS Manufacturing allow uploading of CAD drawings for a free evaluation of the DFM process?
Yes, Our engineers will give you process recommendations and price quotes based on your drawings in 24 hours to help you achieve a balance between manufacturability and cost.
概要
Fiber laser cutting is a good way to cut medium or thin plates in custom sheet metal fabrication and Waterjet cutting is a good choice for thick plates and heat sensitive materials (quality assurance). Material thickness tolerances, and post processes should be considered when deciding both methods.
The right process can save 20%-25% of costs and speed up delivery times. With top notch equipment and technology, LS Manufacturing assists customers in choosing the best balance of cost, quality, and delivery time.
