Advantages: 👉MIG Welding: ➡️Faster welding process, making it suitable for high-production environments. ➡️Easier to learn and use, especially for beginners. ➡️Can weld thicker materials more efficiently. 👉TIG Welding: ➡️Produces high-quality, precise welds with a clean finish. ➡️Provides better control over the weld area, making it ideal for delicate or detailed work. ➡️Less spatter and cleaner welds compared to MIG welding. #Welding #MIGWelding #TIGWelding #MetalWork #PrecisionWelding #WeldingTechniques #Manufacturing #Fabrication #WeldingProjects #WeldingSkills

Groove weld using MIG welding process

Spot welding is a resistance welding method based on pressure + intensity + time .

Speed of laser welding is 3-4times that of Tig /Mig welding . Let’s see how smooth and good looking seam welded by laser . There is another reason you should choose laser welding : easy to be automated.. Electricity Cabinet : stainless steel steel: Thickness 3mm

Alhamdulillah. 🛠️ 𝑻𝒚𝒑𝒆𝒔 𝒐𝒇 𝑾𝒆𝒍𝒅𝒊𝒏𝒈 𝑪𝒓𝒂𝒄𝒌𝒔 Welding cracks are defects in weld joints that can weaken the structure and lead to failures. Here’s a breakdown of the most common types: 1. 𝑯𝒐𝒕 𝑪𝒓𝒂𝒄𝒌𝒔 🔥 𝑾𝒉𝒆𝒏? Occur during welding while the metal is still hot. 𝑾𝒉𝒚? Caused by high temperatures, rapid cooling, or improper filler metal. 𝑪𝒐𝒎𝒎𝒐𝒏 𝑨𝒓𝒆𝒂𝒔: Found in the weld metal or heat-affected zone (HAZ). 𝑬𝒙𝒂𝒎𝒑𝒍𝒆𝒔: Longitudinal cracks (parallel to the weld) and crater cracks. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Use proper preheating, slow cooling, and compatible filler materials. 2. 𝑪𝒐𝒍𝒅 𝑪𝒓𝒂𝒄𝒌𝒔 ❄️ 𝑾𝒉𝒆𝒏? Form after the weld has cooled (hours or even days later). 𝑾𝒉𝒚? Often due to hydrogen entrapment, high residual stress, or low temperatures. 𝑪𝒐𝒎𝒎𝒐𝒏 𝑨𝒓𝒆𝒂𝒔: Usually in the heat-affected zone. 𝑬𝒙𝒂𝒎𝒑𝒍𝒆𝒔: Delayed cracks caused by hydrogen. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Use low-hydrogen electrodes, preheat the metal, and stress-relieve after welding. 3. 𝑺𝒖𝒓𝒇𝒂𝒄𝒆 𝑪𝒓𝒂𝒄𝒌𝒔 🌊 𝑾𝒉𝒆𝒓𝒆? Appear on the surface of the weld. 𝑾𝒉𝒚? Poor welding technique or excessive heat input. 𝑹𝒊𝒔𝒌𝒔: Easily visible but can propagate deep into the weld over time. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Follow proper welding procedures and avoid overheating. 4. 𝑹𝒐𝒐𝒕 𝑪𝒓𝒂𝒄𝒌𝒔 🌱 𝑾𝒉𝒆𝒓𝒆? At the root of the weld, inside the joint. 𝑾𝒉𝒚? Insufficient root penetration or improper alignment. 𝑹𝒊𝒔𝒌𝒔: Hard to detect and can compromise joint strength. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Ensure proper joint preparation and penetration. 5. 𝑻𝒉𝒓𝒐𝒂𝒕 𝑪𝒓𝒂𝒄𝒌𝒔 🎯 𝑾𝒉𝒆𝒓𝒆? Across the weld throat (the middle part of the weld). 𝑾𝒉𝒚? Caused by high stress or improper weld size. 𝑹𝒊𝒔𝒌𝒔: Weakens the weld significantly. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Use appropriate weld size and avoid excessive stress. 6. 𝑪𝒓𝒂𝒕𝒆𝒓 𝑪𝒓𝒂𝒄𝒌𝒔 🌋 𝑾𝒉𝒆𝒓𝒆? At the end of the weld bead. 𝑾𝒉𝒚? Sudden cooling at the end of a weld pass. 𝑹𝒊𝒔𝒌𝒔: May grow into larger cracks. 🛡️ 𝑷𝒓𝒆𝒗𝒆𝒏𝒕𝒊𝒐𝒏: Fill craters properly before stopping the weld. 💡 𝑭𝒊𝒏𝒂𝒍 𝑻𝒉𝒐𝒖𝒈𝒉𝒕𝒔: Welding cracks can compromise safety and durability. Understanding their causes and prevention methods helps ensure strong, defect-free welds. 👉 𝑾𝒉𝒂𝒕’𝒔 𝒚𝒐𝒖𝒓 𝒆𝒙𝒑𝒆𝒓𝒊𝒆𝒏𝒄𝒆 𝒘𝒊𝒕𝒉 𝒘𝒆𝒍𝒅𝒊𝒏𝒈 𝒄𝒓𝒂𝒄𝒌𝒔?
