    It's a shame CC do not send you pictures of the "destructively tested" parts.

    as a fabricator/welder that has to have stuff tested all the time most tubes we weld "pulse" as we can get more heat into the area and stop cold-lap which becomes prone to fractures that get caused by the molten pool running away with itself! i tend to go all the way round a joint and can keep it glowing red for a minute or so after welding! theres possibly a 1/2 second between pulses? its not spot - wait - spot again,its done in quick sucession so as to slow the weld right down and make it more manageable. the fractures associated with impacts are not usually down to the heat from the welding process but from too much or too little pre and post heat.

    Yes it is - at the start of your sentence :)



    I tried googling it, but instead I got a czech porn site. Actually, that might be to do with my google settings and favourites. But back on topic- what's ASME IX please Bill?

    I was chatting with a qualified 'coded' pipe welder earlier (vagobonds) who's been in the welding/fabricating trade for more than 23 yrs.
    Seems there's nowt wrong with the above welds, nor is it any weaker, but prevents excess heat going into the pipe, and is ideal for welding in locations where access is limited.

    I will be doing a cage soon in a joint mk1 project and will be using pulsed technique as it looks easier and neater and no doubt strong enough
