Orbitalum ORBIWELD 19 Micro Orbital Weld Head

Overview

The Orbitalum ORBIWELD 19 is a small, robust closed micro weld head for joining ultra-high-purity and high-performance tubes. Orbitalum, part of ITW Orbital Cutting and Welding in Singen, Germany, describes it as a tool that keeps producing excellent and reliable quality even in difficult conditions and tight spaces. The Orbitalum ORBIWELD 19, or OW 19, covers tube outside diameters from 3.0 mm to 19.05 mm, works in any position, and is completely liquid-cooled for long, uninterrupted welding runs. With the optional conversion kit the same head becomes the ORBIWELD 19 HD, which adds a clamping cassette for inline and prefab work.

Seven Star LLC supplies the Orbitalum ORBIWELD 19, its clamping inserts and the HD conversion kit to fabricators and end users in Oman and the GCC. As a trusted supplier with engineering support in Muscat, we help project teams build a matched package of head, inserts and accessories for their tube list.

How the OW 19 Produces Repeatable Orbital Welds

In a closed orbital weld head the tube ends are clamped in alignment and the tungsten electrode rotates around the joint inside a small chamber filled with shielding gas. The power source controls the arc current, travel speed and gas timing exactly as programmed, so each weld is made the same way. As general welding knowledge, the inside of the tube must also be purged with inert gas to protect the root, and residual oxygen is usually checked before welding begins on high-purity work.

The Orbitalum ORBIWELD 19 makes this routine faster because every Orbitalum orbital welding power source recognises the head and its properties automatically. Before welding the operator only calls up the specified program and starts. The result is a weld that can be reproduced from joint to joint with minimal operator influence, which is the core reason high-purity industries specify orbital welding.

Engineering Design of the Orbitalum ORBIWELD 19

The Orbitalum ORBIWELD 19 uses a three-part clamping mechanism. Orbitalum emphasises that no parts project beyond the head outline even in the open position, so the head can be spread and placed in very tight spaces, and the tubes are aligned exactly and without offset. Practical clamping locks allow one-hand operation, and an optimised scissors clamping system and a flip-up weld head cover called FlipCover make loading and electrode access easier. Markings help when inserting 1.0 mm or 1.6 mm electrodes.

All connections for current, gas and cooling water are integrated into the Orbitalum ORBIWELD 19 itself. The robust aluminium handle carries an integrated control panel, so no additional remote control is needed. The head is supplied with a highly flexible 7.5 m hose package with strain relief, extendable to up to 20.0 m. To increase productivity, the optional ORBITWIN switching unit allows two heads to be used alternately, which Orbitalum says reduces conversion times and downtime considerably.

Key Features

For buyers comparing micro heads, the datasheet lists the following properties of the Orbitalum ORBIWELD 19.

• It welds tubes from 3.0 mm to 19.05 mm (0.118 to 0.750 in) outside diameter.
• It can be used in all positions, whether the tubes to be joined with the Orbitalum ORBIWELD 19 run horizontally, vertically or inclined.
• The head is completely liquid-cooled, giving very high endurance during series welding.
• The three-part clamping keeps all parts within the head outline, even when open.
• An integrated control panel in the aluminium handle replaces a separate remote control.
• Diameter-specific six-part clamping inserts are available in wide and narrow versions.
• Optimised weld gas control and one-hand operation speed up each cycle.
• A conversion kit turns the head into an OW 19 HD with a clamping cassette.

Industrial Applications

Orbitalum names the semiconductor industry, aerospace technology, pharmaceuticals and the supply of high-purity water as the main fields for the Orbitalum ORBIWELD 19. Across Oman and the GCC the same requirements appear in pharmaceutical and food production lines, purified water and water-for-injection loops, hospital and laboratory gas systems, and the small-bore instrument and analyser tubing of refineries, LNG trains and petrochemical complexes in Sohar, Sur and Duqm. Wherever a joint must be smooth, clean and documented, a closed micro head is the usual choice.

Seven Star LLC supplies the Orbitalum ORBIWELD 19 together with clamping inserts in the diameters each project needs, so contractors can mobilise quickly from Muscat to site. Workshops that combine orbital work with manual or semi-automatic welding often also run multi-process sources such as the ESAB Rebel EMP 285ic or the Lincoln Electric Power Wave S500, and heavier structural or vessel jobs may use submerged arc consumables like LongTeng EL8 wire. Related heads and power sources are grouped under orbital pipe welding systems.

Clamping Inserts: Wide and Small Versions

A clamping insert for the Orbitalum ORBIWELD 19 consists of six individual parts, three per side. Type W is the wide version for standard applications, while type S is the small or narrow version for extremely confined spaces. The datasheet table covers sizes such as 3.18, 6.35, 9.53, 12.70, 15.88 and 19.05 mm, plus metric sizes such as 6.00, 10.00, 12.00 and 18.00 mm; a few sizes are offered in only one of the two versions, so the size list should be checked against the table before ordering. Other accessories that Orbitalum recommends include ESG electrode grinders, the ORBmax residual oxygen meter, hose package extensions, WS2 tungsten electrodes and a welding current connection adapter set.
