For example, when welding a 1mm thick plate, the gap should be controlled within 0.1mm. Beyond this range, the laser will pass through the gap, preventing the formation of an effective molten pool. Industry experience shows that for every 0.05mm increase in gap, welding difficulty increases significantly, and the risks of porosity and incomplete fusion also rise.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8580ccf elementor-widget elementor-widget-text-editor\" data-id=\"8580ccf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tThe beam focusing position is crucial.

Negative defocus increases weld depth, forming a deeper molten pool. Positive defocus can be used when welding thin plates, resulting in a larger spot size and dispersed energy, preventing burn-through. The focus position adjustment range is usually within \u00b13mm; precise control requires a high-precision focusing system.

When welding aluminum alloys and titanium alloys, the back side also needs protection to prevent oxidation. Stainless steel can be welded with argon or nitrogen, but aluminum and titanium require high-purity argon (99.99% or higher). The design of the shielding gas nozzle is also crucial, ensuring uniform gas flow over the welding area without dispersing the molten pool.

Insufficient overlap results in insufficient welding area and low strength; excessive overlap wastes material and prolongs welding time. For example, for a 0.8mm upper plate, the overlap should be between 2.4 and 4mm. This rule of thumb applies to most applications, but adjustments should be made based on material type, stress conditions, and operating environment. For areas under high stress, the overlap can be increased to improve the safety factor.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e96125 elementor-widget elementor-widget-text-editor\" data-id=\"9e96125\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tThe laser must have sufficient energy to penetrate the upper plate and melt the lower plate.

Too high a speed may only melt the surface of the upper plate, resulting in a false weld\u2014it may look normal, but lacks actual connection strength. Too slow a speed may cause the upper plate to burn through, creating a deep pit in the lower plate, also leading to weld failure.

For galvanized steel plates, the situation is different; a 0.1mm gap is intentionally left to allow zinc vapor to escape and prevent explosive porosity. Zinc&#8217;s boiling point of 907 degrees Celsius is much lower than steel&#8217;s melting point of 1500 degrees Celsius, causing zinc to vaporize first during welding.

Pulsed welding or low-power continuous welding is usually used, with precise control of heat input.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5ad5913 elementor-widget elementor-widget-heading\" data-id=\"5ad5913\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Advantages<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2e64ad63 elementor-widget elementor-widget-text-editor\" data-id=\"2e64ad63\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li>Smooth and aesthetically pleasing weld seam, with almost invisible welding marks.<\/li><li>No increase in joint thickness.<\/li><li>Suitable for sealing welding of thin plates.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4705291 elementor-widget elementor-widget-heading\" data-id=\"4705291\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Challenges<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0580e22 elementor-widget elementor-widget-text-editor\" data-id=\"0580e22\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li>Suitable only for thin plates, typically limited to below 2mm.<\/li><li>High assembly requirements.<\/li><li>Limited weld strength.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7f66f13 elementor-widget elementor-widget-heading\" data-id=\"7f66f13\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Corner Joint Definition and Application<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b4a889a elementor-widget elementor-widget-text-editor\" data-id=\"b4a889a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tA corner joint is a connection between two plates at a certain angle (usually 90 degrees), with the weld seam located on the outer or inner side of the corner.

The optimal speed needs to be determined through systematic testing, typically by creating a penetration curve (penetration vs. speed) to find the process window that ensures penetration without overheating. This window is usually quite narrow; a speed variation of \u00b110% can affect quality.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-81a313c elementor-widget elementor-widget-text-editor\" data-id=\"81a313c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tThe optimal speed differs for different joint types. Butt joints can be faster because of their high energy efficiency; all molten material is used to form the weld, with no waste. Corner joints and T-joints require slower speeds to allow heat to be fully conducted to the root, ensuring complete root fusion. The root is the weakest point of the joint; poor fusion will severely affect strength. Lap joints require a speed between these two, needing to ensure penetration of the upper plate, avoid burn-through, and ensure complete melting of the lower plate.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-268e087 elementor-widget elementor-widget-text-editor\" data-id=\"268e087\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tSpeed stability is crucial, a problem often overlooked.
