It goes wrong because <strong>travel speed drifts<\/strong>, the <strong>torch angle wanders<\/strong> and the <strong>weave changes width<\/strong> after a few hours of tiring work. A welding carriage takes those three variables out of the operator&rsquo;s hands: it carries the torch at a set speed, holds the angle and, on oscillating models, repeats the same weave on every pass.<\/p>\n<p class=\"a14\">A carriage does <strong>not<\/strong> replace your welding machine. It mechanises motion; the arc still comes from your MIG, TIG or SAW power source and your qualified welding procedure. That makes automation one of the quickest upgrades a fabrication shop can make &mdash; but only if the carriage matches the joint. This guide shows you how to choose.<\/p>\n<div class=\"a15\">\n<h2 class=\"a17\">Manual welding vs a welding carriage<\/h2>\n<div class=\"a16\">What actually changes<\/div>\n<\/div>\n<div

Oscillating models also weave the torch in a programmed pattern, so every pass is repeatable.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">Track or trackless &mdash; which is better?<\/summary>\n<div class=\"a99\">Neither is better everywhere. Trackless carriages such as WeldyFi, Dynex 5M and DynaTwin 200M save setup time on steel fillets. Rail systems such as DynaSwing 100K give slip-free travel on vertical and overhead seams. A flexible track (DynaFlex 100S) suits tank and vessel diameters.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">Can a magnetic welding carriage work on stainless steel or aluminium?<\/summary>\n<div class=\"a99\">Magnets need a steel (ferrous) surface. On stainless steel or aluminium, the carriage has to run on a dedicated track or rail. The MIG, TIG and plasma processes themselves work on these metals.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">Which carriage is best for vertical and overhead welding?<\/summary>\n<div class=\"a99\">DynaSwing 100K uses a rack &amp; pinion drive on a permanent-magnet rail, so it does not slip when climbing. For tank shells, DynaFlex 100S handles vertical and overhead seams on its flexible track, and WeldOrbit 360 works in all positions on its magnetic wheel drive.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">Can one machine both weld and cut?<\/summary>\n<div class=\"a99\">Yes. DynaMove 45K, WeldOrbit 360 and DynaFlex 100S accept plasma or oxy-fuel torches for cutting and bevelling. DynaMove 45K also cuts circles from 200 to 2000&nbsp;mm diameter.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">Does a welding carriage replace my welding machine?<\/summary>\n<div class=\"a99\">No. The carriage mechanises motion and torch position. Welding output still comes from your MIG, TIG or SAW power source and your qualified welding procedure.<\/div>\n<\/details>\n<details class=\"a97\">\n<summary class=\"a98\">What does oscillation (weaving) do?<\/summary>\n<div class=\"a99\">Oscillation moves the torch side to side during travel. It spreads heat across wider joints, improves side-wall fusion in grooves and gives a uniform cap. Adjustable dwell time at each edge helps prevent undercut.<\/div>\n<\/details>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Track, trackless or flexible track? Weave or no weave?
