設計深化：在依據建筑整體風格確定鐵藝欄桿基本樣式后，需對圖紙進行深化設計。詳細標注各部件尺寸，如欄桿立柱管徑、高度，橫桿間距、粗細，雕花圖案尺寸及位置等，確保加工精準度。

Design deepening: After determining the basic style of the iron railing based on the overall architectural style, it is necessary to deepen the design of the drawings. Specify the dimensions of each component in detail, such as the diameter and height of the railing columns, the spacing and thickness of the crossbars, the size and position of the carved patterns, etc., to ensure machining accuracy.

考慮鐵藝與建筑周邊環境協調性，例如臨近道路、花園區域，欄桿高度、通透度要合理規劃，避免視覺阻隔或安全隱患。

Consider the coordination between wrought iron and the surrounding environment of the building, such as near roads and garden areas, and plan the height and transparency of railings reasonably to avoid visual barriers or safety hazards.

材料選用

material selection

主體鐵藝材料優先選用優質低碳鋼，其材質堅韌、可塑性強，便于鍛造復雜造型。材料進場時嚴格檢查表面平整度，不得有裂縫、折疊、分層等缺陷，厚度偏差控制在允許范圍。

High quality low-carbon steel is preferred as the main iron material, which is tough, highly malleable, and easy to forge complex shapes. Strictly inspect the surface flatness when materials enter the site, and there should be no defects such as cracks, folds, or delamination. The thickness deviation should be controlled within the allowable range.

配套的連接件，如鑄鐵花飾與主框架焊接用的焊條，要根據鐵藝材質適配，保證焊接強度，焊條需有正規產品認證標識，確保質量可靠。

The matching connectors, such as the welding rods used for welding cast iron flower decorations to the main frame, should be adapted according to the iron material to ensure welding strength. The welding rods should have formal product certification marks to ensure reliable quality.

加工工藝

Processing technology

切割環節，對于管材或扁鋼等原材料，采用專業切割設備（如數控等離子切割機），精準控制切割尺寸，切割面要光滑平整，切割后及時打磨去除毛刺，防止安裝劃傷工人。

In the cutting process, for raw materials such as pipes or flat steel, professional cutting equipment (such as CNC plasma cutting machines) is used to accurately control the cutting size. The cutting surface should be smooth and flat, and burrs should be removed in a timely manner after cutting to prevent installation scratches on workers.

彎曲成型工藝，依據設計弧度，利用專業彎管機操作，確保弧度自然流暢，不變形、不開裂；鍛造花飾、圖案時，嚴格按照模具或手工精細打造，保證花紋清晰、立體感強。

Bending forming process, based on the designed curvature, using professional pipe bending machine operation to ensure natural and smooth curvature, without deformation or cracking; When forging floral decorations and patterns, they are strictly crafted according to the mold or by hand to ensure clear patterns and strong three-dimensional sense.

焊接工序為關鍵環節，采用氬弧焊或二保焊，由經驗豐富焊工施焊，焊縫要均勻飽滿，無氣孔、夾渣，焊接完成后進行外觀打磨處理，使焊點與母材融合自然，整體美觀。

The welding process is a critical step, using argon arc welding or double protection welding, and welded by experienced welders. The weld seam should be uniform and full, without pores or slag inclusions. After welding is completed, the appearance should be polished to make the welding point blend naturally with the base material, and the overall appearance should be beautiful.
