Z18 Self Alignment H Beam Assembly Machine with Manual Tack Welding


The 3 models of Z15~Z20 I Beam Assembly Machine with Tack Welding have similar working steps as introduced previously.


As supplement,

  1)  For the advantages of manual CO2 tack welding compared with automatic, besides its relative lower investment on equipment purchase, another is consequently less maintenance& service job (Less potential trouble points thanks to removal of PLC/ Inverter/ And subsequent assistant mechanical unit);

  2)  Meanwhile, manual CO2 tack welding also has its disadvantages:

      -  Need 2 operators carry out welding at the same time (They should stand at both sides of the machine, and weld 2 seams on both sides of the workpiece together), instead of only 1 operator in automatic welding;

      -  Compared with consistent welding seams generated in automatic CO2 tack welding, manual work usually delivers welded H Beam of obvious more variation, which poses great challenge on welding process quality control;

   3)  Generally speaking, in China, up to now in purchase of automatic I Beam Assembly machine, manual welding is more often selected than automatic welding; While for exported I Beam Assembly machine, automatic CO2 tack welding sees more application;

    4)  As can be observed from working process of I Beam Assembly machine with tack weld, during its one round of complete operation cycle, the workpiece of H Beam needs to be travelled thru the automated I Beam Assembly machine 2 times:

       -  The 1st time assembled and welded into ⊥-shape, with the 1st and 2nd seams welded;

        - The 2nd time assembled and welded into 工-shape, with the 3rd and 4th seams welded;

        -  During this process, travel crane is used for flipping and sending back the ⊥-shape workpiece back to input

            of the machine. So automatic I Beam Assembly machine with tack weld needs to be installed at the location

            with travel crane available overhead;

  5) For CO2 tack welding machine, in automatic welding version we equipped the model of 350A welding current

       of either Chinese domestic or Japan brand. While in manual welding, usually customer prepares it. So, 

       sometimes it is 350A, and sometimes 500A, Both 2 options are feasible on the use of automatic I Beam 

       Assembly machine with tack welding.
