Product Name: Automatic Horizontal Seam Welding Machine (AGW) /Tank Construction Machinery Model NO.: AGW-LNG-I Type: Middle Pressure Storage & Transportation Equipment Tank Marerial: metal Tank Certification: ISO9001, GS Customized: Non-Customized Condition: New Power Source: Miller/Lincoln Application Field: Water/Oil&Gas Tank Trademark: WINCOO Transport Package: Container Specification: SGS, ISO9001, CE Origin: Nanjing, China HS Code: 851531900 Product Description Cost and efficiency comparison analysis between manual welding and automatic welding on tank constructionI, Welding materials consuming cost comparisonFor the storage tank girth seam welding, usually it takes X bevel if by manual welding while we consider K type bevel during automatic girth welding machine using. Take 60mm tank shell plate with 10 meters welding workload for example, the required welding materials that will be consumed is like this.A, based on 60°X bevel by Manual welding, the calculation of required quantity of welding materials in the seam is: Gap G=2mm,δ=60mm,F=0,Bevel degree 60°for example: Deposition metal rate=2×60+30×tg30°×2×30/2×2+(2×30×tg30°+2)×3×2/3×2mm2×10m×7.8g/cm3 =101.85kgWelding wire=101.85kg/0.9=113.16kgWelding flux=1.8×113.16kg=203.00kgB, :based on 45°K bevel by automatic girth seam welding machine welding, the calculation of required quantity of welding materials in the seam is:Gap G=2mm,S1=60mm,F=0,Bevel degree 45°for example:Deposition metal rate=2×60+60/2×tg45°×60/2+(30×tg45°+2)×3×2/3×2mm2×10m×7.8g/cm3 =89.54kgWelding wire=89.54kg/0.9=99.50kgWelding flux=1.2×99.50kg=119.40kgØ Materials Cost will be saved: Each 10 meters seam welding can reduce welding materials cost:Around USD 40.00;1, Each 10 meter can reduce cost for welding wire of 24kg, which is also Around 35 USD;2, Welding flux can reduced cost of 5 USD for each 10 meters;, Man-hour cost / welding Time comparison between manual welding and automatic machine weldingTake 50mm shell plate girth seam welding for exampleWelding processWelding wire DiameterWelding powerWelding speed mm/minBevel typeWelding pass quantity10M Seam welding time requriedMan-hour cost (please refer to your local salary cost)10m seam welding man-hour cost differenceManual welding¢1.6-2.0mm-250A-20060°X type Bevel50 passesAround 55hoursAutomatic machine welding¢3.2mm-500A-500mm/min45°K type bevelAround 22passesAround 9.2hoursNotes:1,The automatic welding machine is with 6-8 times faster than by manual2,It can greatly shorten your tank construction time which may reduce your project cost.
